• Item No Preview Available ON-CHIP VANADIUM DIOXIDE-BASED SWITCHABLE DEVICES ON SILICON PHOTONIC PLATFORM Gregory, Beti Tanyi ( 2023-09 ) In today's technological landscape, the radio frequency (RF) range plays a pivotal role, particularly in applications such as sensors, wireless technologies, satellites, and the Internet of Things. Meeting the ever-growing demands for enhanced resolution, bandwidth, speed, and on-chip space necessitates access to carrier frequencies reaching into the hundreds of gigahertz (GHz) and terahertz (THz) ranges. Traditional receiver technology, however, grapples with limitations in signal processing, amplification, and mixing, creating a significant bottleneck for the operation of such high-frequency systems. This thesis presents a series of integrated photonic devices on silicon-on-insulator which harness the properties of vanadium dioxide (VO2) to create integrated modulators and switches with improved performance and reduced platform while also leverage the field enhancement enabled by plasmonics. The initial investigation introduces the simulation of a hybrid orthogonal plasmonic modulator with a small footprint and a remarkably compact modulating section measuring just 100nm x 100nm. At its core, this modulator leverages the extraordinary electro-optic properties of Vanadium dioxide to facilitate intensity modulation. While the modulator has been meticulously optimized for the 1550 nm telecommunications wavelength, it also demonstrates remarkable versatility, capable of operating across a broad wavelength spectrum. We then present the simulation of compact epsilon-near-zero electro-optic modulator, incorporating a Vanadium dioxide nanorod array into a silicon strip waveguide. The compact modulator with dimensions of just 1.6 micrometers x 1 micrometers capitalizes on the first order metal-insulator transition of vanadium dioxide, coupled with the epsilon-near-zero effect to demonstrate a potent non-linear response. Furthermore, the research delves into the intricate role of nanorod layering, shedding light on how each layer contributes to modulation depth. This analysis culminates in the proposal of a novel hexagonal nanorod geometry, featuring evenly spaced nanorods, which drastically reduces insertion loss, boosts modulation index, and broadens the operational wavelength range, compared to the initial design. These findings open doors to the development of high-speed nanoscale modulators and ultra-thin thermal switches. Furthermore, we introduce a compact and thermally reconfigurable photonic switch that capitalizes on drop-cast vanadium oxide nanoparticles. This device boasts a wide operating wavelength range and impressive extinction ratios across the telecom wavelengths. Significantly, this marks the inception of the first-ever vanadium oxide nanoparticle-based thermally reconfigurable photonic switch, characterized by its accelerated phase transition and minimal hysteresis. With its versatile operating range and scalable fabrication process, this innovation paves the way for the creation of ultracompact photonic switches and modulators, revolutionizing optical communication systems. Lastly, our thesis presents a compact plasmonic neuromorphic device, showcasing both thermal and electronic reconfigurability, alongside simultaneous optical and electrical readouts. The dual readout ability of this device allows is a key feature as it allows simultaneous logic and memory mimicking the neurons and synapses of the brain. The plasmonic neuromorphic switch shows an accelerated phase transition with a small hysteresis. With potential across a broad wavelength spectrum and a scalable fabrication process, integrating vanadium oxide nanoparticles into plasmonic slots emerges as a promising path for on-chip plasmonic switches and advances in optoelectronic neuromorphic computing devices featuring in-memory computing capabilities. In summation, this thesis explores compact, high-performance integrated optical modulators, switches, and compact platforms for facilitating the direct interaction of radio frequency and optical signals in a single chip with applications in making single chip optical communication devices, converting RF signals directly to optical signals, sensing, and neuromorphic computing.

• Item No Preview Available A Multifunctional Smart Field-Programmable Radio Frequency Surface Li, Tianzhi ( 2023-04 ) Wireless communication technology has completely transformed the way we communicate and access information. It operates on the principles of electromagnetic wave propagation, as described by Maxwell's equations. The scope of wireless communication is vast and includes satellite communication, handheld device communication, and Internet of Things (IoT), which have revolutionized fields of industry, healthcare, transportation, education, and entertainment. As demand for faster and more reliable communication continues to grow, a range of wireless communication standards has been developed, including WiFi, BLE, cellular networks, near-field communication (NFC), and ZigBee, each operating at a unique frequency range. Antennas that can operate across multiple communication standards have remained a challenge due to the interdependent factors of antenna geometry, size, and RF characteristics. As the number of devices with wireless connectivity increases dramatically, the spectrum resource is getting limited, which results in congestion and reduced performance. Reconfigurable antennas have been intensively studied in the last few decades to mitigate this challenge. Although reconfigurability in operating frequency, radiation pattern and polarization have been implemented, limitations including lack of programmability, pattern diversity, and self-adaptive capability against environmental interference exist. To address these limitations, we proposed a new concept called Field-programmable RF surface (FPRFS), which allows for the control of current flow on the surface to achieve desired antenna characteristics and impedance matching capabilities. This work starts with the theoretical analysis and creates the mathematical model for the FPRFS in antenna, impedance matching network, and filter applications. Our research demonstrated the reconfigurability of FPRFS antennas in operating frequency, radiation pattern, and polarization reconfigurability with radiation gain and efficiency levels that are comparable to those of conventional fixed patch antennas and enhanced immunity to surrounding obstacles. We developed a software algorithm for the FPRFS that enables it to automatically optimize its configuration in real-time, thereby adapting to changing load impedance or environmental interferences.

• Publication RF Amplification and Filtering Techniques for Cellular Receivers ( University College Dublin. School of Electrical and Electronic Engineering, 2021 ) Bozorg, Amir   The usage of various wireless standards, such as Bluetooth, Wi-Fi, GPS, and 4G/5G cellular, has been continually increasing. In order to utilize the frequency bands efficiently and to support new communication standards with lower power consumption, lower occupied volume and at reduced costs, multimode transceivers, software defined radios (SDRs), cognitive radios, etc., have been actively investigated. Broadband behavior of a wireless receiver is typically defined by its front-end low-noise amplifier (LNA), whose design must consider trade-offs between input matching, noise figure (NF), gain, bandwidth, linearity, and voltage headroom in a given process technology. Moreover, monolithic RF wireless receivers have been trending toward high intermediatefrequency (IF) or superhetrodyne radios thanks to recent breakthroughs in silicon integration of band-pass channel-select filters. The main motivation is to avoid the common issues in the currently predominant zero/low-IF receivers, such as poor 2nd-order nonlinearity, sensitivity to 1/f (i.e. flicker) noise and time-variant dc offsets, especially in the fine CMOS technology. To avoid interferers and blockers at the susceptible image frequencies that the high-IF entails, band-pass filters (BPF) with high quality (Q) factor components for sharp transfer-function transition characteristics are now required. In addition, integrated low-pass filters (LPF) with strong rejection of out-of-band frequency components are essential building blocks in a variety of applications, such as telecommunications, video signal processing, anti-aliasing filtering, etc. Attention is drawn toward structures featuring low noise, small area, high in-/out-of-band linearity performance, and low-power consumption. This thesis comprises three main parts. In the first part (Chapters 2 and 3), we focus on the design and implementation of several innovative wideband low-noise (transconductance) amplifiers [LN(T)A] for wireless cellular applications. In the first design, we introduce new approaches to reduce the noise figure of the noise-cancellation LNAs without sacrificing the power consumption budget, which leads to NF of 2 dB without adding extra power consumption. The proposed LNAs also have the capability to be used in current-mode receivers, especially in discrete-time receivers, as in the form of low noise transconductance amplifier (LNTA). In the second design, two different two-fold noise cancellation approaches are proposed, which not only improve the noise performance of the design, but also achieve high linearity (IIP3=+4.25 dBm). The proposed LN(T)As are implemented in TSMC 28-nm LP CMOS technology to prove that they are suitable for applications such as sub-6 GHz 5G receivers. The second objective of this dissertation research is to invent a novel method of band-pass filtering, which leads to achieving very sharp and selective band-pass filtering with high linearity and low input referred (IRN) noise (Chapter 4). This technique improves the noise and linearity performance without adding extra clock phases. Hence, the duty cycle of the clock phases stays constant, despite the sophisticated improvements. Moreover, due to its sharp filtering, it can filter out high blockers of near channels and can increase the receiver’s blocker tolerance. With the same total capacitor size and clock duty cycle as in a 1st-order complex charge-sharing band-pass filter (CS BPF), the proposed design achieves 20 dB better out-of-band filtering compared to the prior-art 1st-order CS BPF and 10 dB better out-of-band filtering compared to the conventional 2nd-order C-CS BPF. Finally, the stop-band rejection of the discrete-time infinite-impulse response (IIR) lowpass filter is improved by applying a novel technique to enhance the anti-aliasing filtering (Chapter 5). The aim is to introduce a 4th-order charge rotating (CR) discrete-time (DT) LPF, which achieves the record of stop-band rejection of 120 dB by using a novel pseudolinear interpolation technique while keeping the sampling frequency and the capacitor values constant.   139
• Publication Frequency Control of Virtual Power Plants ( University College Dublin. School of Electrical and Electronic Engineering, 2022 ) Zhong, Weilin   ; 0000-0001-6737-4873 The Virtual Power Plant (VPP) concept refers to the aggregation of Distributed Energy Resources (DERs) such as solar and wind power plants, Energy Storage Systems (ESSs), flexible loads, and communication networks, all coordinated to operate as a single generating unit. Using as starting point a comprehensive literature review of the VPP concept and its frequency regulation technologies, the thesis proposes a variety of frequency control and state estimation approaches of VPPs, as follows. First, the thesis studies the impact of coordinated frequency control of VPPs on power system transients, in which ESSs are utilized to provide fast frequency regulation. The thesis also proposes a simple yet effective coordinated control of DERs and ESSs able to integrate the total active power output of the DERs, and, thus, to improve the overall power system dynamic performance. The impact of topology on the primary frequency regulation of VPPs is also investigated. With this regard, two types of VPPs topologies are considered, that is, a topology where the DERs that compose the VPP are scattered all-over the transmission grid; and a topology where the DERs are all connected to the same distribution system that is connected to the rest of the transmission grid through a single bus. Next, the thesis proposes a control scheme to improve the dynamic response of power systems through the automatic regulators of converter-based DERs. In this scheme, both active and reactive power control of DERs are varied to regulate both frequency and voltage, as opposed to current practice where frequency and voltage controllers are decoupled. To properly compare the proposed control with conventional schemes, the thesis also defines a metric that captures the combined effect of frequency/voltage response at any given bus of the network. Finally, the thesis presents an on-line estimation method to track the equivalent, time-varying inertia as well as the fast frequency control droop gain provided by VPPs. The proposed method relies on the estimation of the rate of change of the active and reactive power at the point of connection of the VPP with the rest of the grid. It provides, as a byproduct, an estimation of the VPP’s internal equivalent reactance based on the voltage and reactive power variations at the point of connection. Throughout the thesis, the proposed techniques are duly validated through time domain simulations and Monte Carlo simulations, based on real-world network models that include stochastic processes as well as communication delays.   183
• Publication Low-Complexity Digital Predistortion for 5G Massive MIMO and Handset Transmitters ( University College Dublin. School of Electrical and Electronic Engineering, 2022 ) Wang, Xiaoyu   The demand for new wireless communication systems to support high mobility and low latency necessitates a rethink of the architecture of wireless communication systems as well as the design of their key components. This thesis presents several novel techniques to solve the major challenges in digital predistortion (DPD) for millimeter wave multi-input multi-output (MIMO) and handset transmitters to lower the hardware cost and computational complexity of the fifth generation (5G) communication systems. The first part of the thesis focuses on the architecture of the MIMO DPD solution for 5G transmitters. To extract DPD model coefficients, a feedback data acquisition path is required. In conventional single-input single-output (SISO) systems, the output is usually acquired directly from the power amplifier (PA) with a coupler. In massive MIMO systems, the number of RF chains is large. Using dedicated feedback paths for each PA separately is not feasible. To lower the hardware cost, a novel data acquisition scheme is proposed to obtain the output signals in far field over the air (OTA) using a single antenna and feedback loop, and then reconstruct the output of each PA. Simulation and experimental results demonstrate that the proposed OTA data acquisition can accurately reconstruct the output of each PA in the MIMO systems and the DPD solutions derived from the reconstructed data can successfully linearize the nonlinear MIMO transmitters. In the multi-user scenario, the nonlinearity of the transmitters varies with the movement of user equipments (UEs), and the DPD model coefficients need to be updated accordingly. To meet the requirement of high mobility, the complexity of the system update must be low. In the second part of the thesis, we present a new DPD system, where DPD model can be updated fast and accurately without capturing PA output or applying costly model extraction algorithms. In the proposed method, nonlinear characteristics of the PA are encoded into low-dimensional PA features using feature extraction algorithms. To identify DPD model coefficients, PA features are extracted first and the DPD model coefficients are then generated directly by DPD generator with PA features. Experimental results show that the proposed DPD solution can linearize PA with very low complexity compared to that using the conventional solutions. Finally, the focus shifts to handset transmitters. Conventionally, DPD is usually deployed for high power base stations. With the continuously increasing bandwidth, DPD may also be required for handset PAs in 5G communication systems. Different from the models used for base stations, DPD model for handset PAs must have very low complexity because of the stringent power budget limit. At the same time, the tolerance for load mismatch must also be considered. The third part of the thesis analyzes the characteristics of handset PAs with load mismatch and introduces a low-complexity DPD model based on magnitude-selective affine (MSA) function. Experimental results demonstrate that the extended MSA (EMSA) model shows better linearization performance while keeping much lower complexity than the conventional DPD models.   60
• Publication Circularly Polarized Antennas for 5G Millimetre-Wave Communications ( University College Dublin. School of Electrical and Electronic Engineering, 2022 ) Sadeghi-Marasht, Samaneh   The need of a higher data rate, lower latency, and cost efficiency led to the fifth-generation (5G) emerging as a new communication standard. This generation includes many unused frequencies with high available bandwidth channels that can provide higher capacities such as millimeter-wave (mm-wave) bands. One of the main challenges of working at high frequencies of this generation is path loss that needs to be addressed. To overcome this issue, a high gain antenna with a small size is required. Consequently, the first major question arises: how to effectively increase the gain and efficiency of the antenna at a high frequency with a small size. Importantly, it is vital to transport as much as data is possible without any sensitivity to the alignment of the transmitter or receiver antenna that can be satisfied by using circularly polarized (CP) radiating waves. Thus, the second research question emerges: how to provide high gain small size antenna with CP at high frequencies. To address the first two major research questions in this thesis we designed a miniature dual-band CP antenna that works at 28 GHz and 38 GHz with high gain. This antenna can be implemented in mobile devices, unmanned aerial vehicles (UAVs), and base stations (BSs) because of the small sizes of 11 × 14 × 0.508 mm3. For getting a deep insight into the structure and the design procedures of the dual-band antenna, characteristic mode analysis (CMA) is employed. Note that the CMA is not sensitive to the feeding position and the material in this analysis is not lossy. Therefore, after using CMA, the optimization is conducted in the full-wave simulation as the feeding is added to the structure, and the material is lossy. The single CP antenna covered the bands of 27-28.4 GHz and 34.7-40 GHz, with a maximum gain of 6.3 dBiC and 5.51 dBiC at 28 GHz and 38 GHz, respectively, whereas the radiation efficiency is 94% and 96% with the ARBW of 2.5% and 1.5%. A phased antenna array is then constructed to provide a higher gain for this designed dual-band antenna. In a phased antenna array we consider four designed single element antennas close to each other to create a 2 × 2 antenna array with high gain at 28 GHz and 38 GHz. For a 4 × 4 antenna array, an electromagnetic band-gap (EBG) is used to reduce the mutual coupling between elements in the array. The radiating signals will be sent to different users with circular polarization via electronic beamforming. The position of each antenna element is also optimized to provide the constructive radiating wave towards our desired directions. The array was able to steer the beam between -26.5 to 29.5 degrees for the lower band and -29.5 to 35.5 degrees for the higher band with the maximum gain of 12.8 dBiC and 11.5 dBiC, respectively. Another method to enhance the gain is implementing a lens structure in front of the radiating antenna. Here, a significant challenge is to maintain the CP of the incoming CP wave while the gain is increased. Therefore, the third research question is how to design a lens with the capability of enhancing the gain and keeping the CP when the lens is fed by a CP antenna source. Concerning the third major research question, in this thesis, we designed a CP lens structure. First, a multi-layer lens with a thickness of 2.03 mm was designed, and then a one-layer lens structure with a thickness of just 0.508 mm was made. The lens was located in front of different radiating antennas. These lens structures resulted in significant gain enhancement for various feeding antennas working at 28 GHz. The unit cell of the one-layer lens can provide a broad phase shift compared to the multi-layer counterpart. The proposed lens structures not only increased the gain of the incoming CP wave but also kept its polarization to overcome the issues of reflectivity, absorption, inclement weather, and mis   16
• Publication Contributions to the theory and development of low-jitter bang-bang integrated frequency synthesizers ( University College Dublin. School of Electrical and Electronic Engineering, 2022 ) Avallone, Luca   The advent of next-generation wireless standards demands ever-increasing data-rate communication systems. It mainly involves a higher carrier frequency to take advantage of wider bandwidth channels and more complex modulation schemes to pack more information into each symbol. In this context, the bottleneck is represented by the frequency synthesizer used to generate the local oscillator signal for the transceiver, which has to operate under stringent low output jitter requirements. Such performance must be provided at low power dissipation and area consumption in order to meet the requirements of low-cost and high integration level of the modern communication systems. The digital phase locked loop architecture can meet the required jitter performance while synthesizing fractional-N frequencies. Such PLLs offer significant advantages over their traditional analog counterpart in terms of area occupation, flexibility and scalability in advanced deep sub-µm CMOS technologies. The digital PLL topology based on a bang-bang phase detector, denoted bang-bang PLL, which is a single bit digital phase detector, leads to a less complex and more power-efficient architecture, but, on the other hand, it also introduces a hard nonlinearity in the loop, making the analysis of the bang-bang topology more challenging than in the multi-bit case. A comprehensive phase noise analysis of bang-bang digital PLLs is presented which overcomes the limitations of previous models and it is valid in all cases where physical noise sources (i.e. reference and DCO) are dominant with respect to quantization errors. In particular, (i) input-referred jitter is estimated by means of a linear time-domain analysis derived from a nonlinear DPLL model, and (ii) phase noise spectra are predicted using a discrete-time domain model that accounts for time-variant effects that arise from the intrinsic multirate nature of the DPLL. The possibility of accurately determining the DPLL jitter and phase noise spectra, enabled by the novel analysis presented in this thesis, is key to significantly speeding up the design-space exploration phase, since it allows one to perform quick and precise parametric sweeps. However, even when designed properly, bang-bang PLLs are affected by the unavoidable bang-bang phase detector quantization noise, which is added on top of the intrinsic reference and DCO phase noise. The quantization noise can be appreciated in the PLL's output spectrum as increased in band noise with respect to the analog counterpart, that, in fact, still achieves superior performance in terms of jitter-power. This results in worse integrated jitter performance for the same intrinsic levels of reference and oscillator phase noise. To overcome the binary phase detector quantization noise in DPLLs, state-of-the-art works rely on a multi-bit time-to-digital converter to digitize the PLL phase error with a physical resolution below the input jitter, leading to increased design complexity, with an associated area and power penalty. In order to overcome the ultimate limit of the bang-bang PLL, a digital PLL based on a bang-bang phase detector with adaptively optimized noise shaping has been fabricated in a 28nm CMOS process. The prototype occupies a core area of 0.21 mm2 and draws 10.8 mW power from a 0.9 V supply. The integrated jitter is 69.52 fs and 80.72 fs for the integer-N and the fractional-N case, respectively. Achieving a jitter-power figure-of-merit of -251.5 dB in fractional-N mode, the proposed system effectively bridges the gap to analog implementations. The first chapter of this work is introductory, and is intended to give some background information needed to underpin the remaining part of the thesis. The following chapters, 2, 3 and 4, collect the results achieved during the PhD activity, and each of them is associated with a publication. In the last chapter, conclusions are drawn and the open points are discussed in order to be considered for future work.   280

• Senior Thesis

For an A.B. degree, a research thesis is strongly encouraged but not required; a thesis is necessary to be considered for High or Highest Honors. Additionally, a thesis will be particularly useful for students interested in pursuing graduate engineering research. 

In the S.B. degree programs, every student completes a design thesis as part of the required senior capstone design course (ES 100hf). During the year-long course students design and prototype a solution to an engineering problem of their own choice.

The guide below provides an overview of the requirement for an A.B. thesis in Electrical Engineering:

• Built a power conversation circuit to drive a >500 V load for in -flight system using a small form factor lithium ion battery

Engineering A.B. Thesis Extensions and Late Submissions

Thesis extensions will only be granted in extraordinary circumstances, such as hospitalization or grave family emergency. An extension may only be granted by the DUS (who may consult with thesis advisor, resident dean, and readers). For joint concentrators, the other concentration should also support the extension. To request an extension, please email your ADUS or DUS, ideally several business days in advance. Please note that any extension must be able to fall within our normal grading, feedback, and degree recommendation deadline, so extensions of more than a few days are usually impossible.

Late submissions of thesis work will not be accepted. A thesis is required for joint concentrators, and a late submission will prevent a student from fulfilling this requirement. Please plan ahead and submit your thesis by the required deadline.

Senior Thesis Submission Information for A.B. Programs

Senior A.B. theses are submitted to SEAS and made accessible via the Harvard University Archives and optionally via  DASH  (Digital Access to Scholarship at Harvard), Harvard's open-access repository for scholarly work.

In addition to submitting to the department and thesis advisors & readers, each SEAS senior thesis writer will use an online submission system to submit an electronic copy of their senior thesis to SEAS; this electronic copy will be kept at SEAS as a non-circulating backup. Please note that the thesis won't be published until close to or after the degree date. During this submission process, the student will also have the option to make the electronic copy publicly available via DASH.  Basic document information (e.g., author name, thesis title, degree date, abstract) will also be collected via the submission system; this document information will be available in  HOLLIS , the Harvard Library catalog, and DASH (though the thesis itself will be available in DASH only if the student opts to allow this). Students can also make code or data for senior thesis work available. They can do this by posting the data to the Harvard  Dataverse  or including the code as a supplementary file in the DASH repository when submitting their thesis in the SEAS online submission system.

Whether or not a student opts to make the thesis available through DASH, SEAS will provide an electronic record copy of the thesis to the Harvard University Archives. The Archives may make this record copy of the thesis accessible to researchers in the Archives reading room via a secure workstation or by providing a paper copy for use only in the reading room.  Per University policy , for a period of five years after the acceptance of a thesis, the Archives will require an author’s written permission before permitting researchers to create or request a copy of any thesis in whole or in part. Students who wish to place additional restrictions on the record copy in the Archives must contact the Archives  directly, independent of the online submission system. 

Students interested in commercializing ideas in their theses may wish to consult Dr. Fawwaz Habbal , Senior Lecturer on Applied Physics, about patent protection. See Harvard's policy for information about ownership of software written as part of academic work.

Determine the Project's Scope.

Do you know what you are looking for?  Can you describe your project using one simple sentence or can you phrase the project as a question?  Without a clear idea of the project, you may not be able to determine which are the best resources to search, what terminology should be used in those resources, and if the results are appropriate and sufficient.    

If you're having difficulty getting your project described succinctly, try using a PICO chart to identify the concepts involved:

• P is the popluation, problem, predicament or process
• I is the intervention or improvement
• C is what you'll compare your intervention/improvment to, and
• O is the outcome (or results of the comparison of I and C ) 

For example: 

Your client, the owner of a nuclear power generating facility, has had several less than optimal safety inspections recently.  The inspectors have singled out operator error as a major concern and have required changes in employee training.  But is more training the solution?  The employees complain that the plant's poorly designed control room hampers their ability to respond to non-standard situations.  Could a redesign improve performance and decrease the occurance of unsafe events?   Your client wants more than just your opinion, he wants to see the data to back it up.   So, what can you find in the literature?

Here's one way that the PICO chart could be filled out:     

• P =   nuclear power safety  
• I  = human factors engineering
• C  =  additional training; little or no human factors engineering used  
• O = accident rate or safety inspection comparison

And here are examples of possible search statements:  

• I am looking for ways that human factors engineering can improve safety in the nuclear power industry.
• Is additional training or employing human factors engineering the better method for reducing safety violations in a nuclear power plant? 

Your research will always start with a " P AND I " search; those are the most important pieces of the puzzle.  However, once you have the results from that search, you'll need to know where you want to go with those results; that's when the C and O concepts need to be considered.  

 Also, don't forget --- determine if your project has limits.  For example:

• Are you reviewing the literature only within a specific time frame?
• Are you looking at English-language material only?
• Are you considering research from just the United States or worldwide?
• Are there types of material you won't be covering (trade magazines, patents, technical reports, etc.)?  

Take the simple sentence or question that describes what you are looking for.  What are the concepts in the sentence? Are there synonyms that describe the same concept?   If you filled out a PICO chart, concentrate on the  P (problem) and the  I (intervention) for the concept chart.  

Concept Chart:

Concept 1:   _______  OR _______  OR _______  AND Concept 2:   _______   OR   _______  OR   _______  AND Concept 3:  _______  OR  _______  OR   _______ 

  Example:  

I am looking for ways that human factors engineering can improve safety in the nuclear power industry. 

Concept 1:   nuclear power    OR _ nuclear industry _____   AND Concept 2:   _safety___  OR   _accident prevention____   AND Concept 3: _ human factors engineering ___   

What resources you'll use for your literature review depends on what types of materials you want to find.  

• Background Information The more you know about a topic, the better you'll be able to research it.  You'll be familiar with the terminology, understand the underlining science/technology and be aware of the issues in the field. Most importantly, you'll be able to understand what you've retrieved from your search.  But no matter how much you know before hand you'll likely run across terms and concepts with which you're unfamiliar.    Materials such as encyclopedias, dictionaries and handbooks will not only help you learn about the basics of your topic before you begin your search but they'll also help you understand the terminology used in the documents you found from your literature review.    You'll find these types of resources listed on the Dictionaries and Handbooks pages on this guide.
• Books The large size of books (usually 100-500 pages) allows a topic to be studied braodly, covering many different issues.  Conversely, the large size also allows for a specific aspect of the topic to be covered in great detail.  Because of the time it takes to publish, sci-tech books generally do not contain the most current information. To find print and online books from both the ASU Library as well as in other libraries, see the Books page on this guide.
• Conference Papers Scientists and engineers frequently present new findings at conferences before these findings are written up in journal articles or books.  Not every conference, however, publishes it proceedings.  In some cases, conferences publish only a few of the papers presented but not all.   Many resources that help you find journal articles, may also be used to find conference papers, see the Articles page on this guide.
• Journal and Trade Magazine Articles Articles in journals (also called magazines) are short, usually 5-20 pages in length and cover a specific finding, experiment or project.  Articles in scholary journals are usually written by academics or professional scientists/engineers and are aimed at others at the same level.   Articles in trade journals/magazines are written by the journal staff and report on industry news suchs as sales, mergers, prices, etc.   To find journal and trade magazine articles, use the resources listed on the Articles page on this guide. 
• Patents Patents are grants from governments that gives the inventor certain rights of manufacture.  Patents provide a wealth of information for how a technology is being advanced and by which companies.  It is frequently stated that 80% of the information in patents never appears elsewhere in the literature. 
• To identify patents granted in the U.S. and internationally see the " Searching for Patents " guide.
• To see statistical information for U.S. patents by technology class see the US Patent and Trademark's website.
• Technical Reports Technical reports are part of the "gray literature";  gray literature refers to documents that are not published commercially, hence they are difficult to both identify and find.  Technical reports focus on a specific experiment or research project and are meant to convey the results of the experiment or project back to the funding organization.  In the United States, common sources of technical reports are the government agencies that sponsor research projects.  Reports generated within a private corporation and funded soley by that corporation are seldom ever available to anyone outside of the company.      To find technical reports, use the resources listed on the Technical Reports page on this guide.     

Search, Read, Refine and Repeat

Now it's time to apply your search strategy in the resources you've decided to use.

• Use the Advanced Search feature (or whatever search is set up with the 3 lines of boxes) and enter your search strategy just as you recorded in your search strategy chart.  Don't forget to set your limits.   If the resource only provides a single search box, rearrange your chart from vertical into horizontal so that the search statement looks like this:   (Concept#1 OR synonym) AND (Concept#2 OR synonym) AND (Concept#3 OR synonym) Example: (nuclear power OR nuclear industry) AND (safety OR accident prevention) AND (human factors engineering)
• Examine the results to find the most appropriate items.  Keep your one-sentence project description (and/or your PICO chart) in mind to help you stay on track.
• Export the records/citations you want to keep into a citation manager.
• If there are subjects (may also be called subject headings, index terms, descriptors or controlled vocabulary) assigned to each item, make sure that those also transferred into a citation manager.  If not, add them manually.
• Get the full text of the items 
• Read the full text of the items and look at the subjects assigned to the item and consider:
• Do I have to change (narrow) my topic to something more specific because I'm finding way too much? 
• Do I have to change (broaden) my topic because I can't find enough about it? 
• Is there additional terminology for my topic/concepts that I hadn't included in my original search?
• Redo your search strategy according to what you found in step #6 and rerun the search in the resources again.
• You may need to repeat this cycle several times before you are able to identify the best terminology to use in each resource. 

If there will be several months in between when you search the literature and when you turn in the paper, consider setting up alerts and feeds so that you are notified should new items about your topic appear.   How you set up an alert or feed will vary.  In most cases you'll be required to set up a personal account or profile with the journal or database --- there is no charge for this but you will have to identify yourself and provide an email address.  

For instructions on setting up alerts and feeds, see the " Keep Current " page.
