Investigation and development of wideband antenna gain enhancement techniques
(2023)The far-field gain of an antenna relies on its physical dimensions, often posing a challenge for achieving higher gain without increasing size. We address this issue by exploring innovative design strategies to enhance the ... -
Efficient Automated Generation of Local Descriptors for Use in ab initio Electronic Structure Simulations
(2023)First-principles electronic structure calculations based on density functional theory (DFT) are well-known to have a high computational cost that scales algorithmically as O(N³), where N is the number of electrons. Reducing ... -
Function Implementation in a Multi-Gate Junctionless FET Structure
(2023)This dissertation explores designing and implementing a multi-gate junctionless field-effect transistor (JLFET) structure and its potential applications beyond conventional devices. The JLFET is a promising alternative to ... -
Effective Surface Areas and Adsorption Capacity of Graphene with Vacancies
(2023)Graphene has been heavily researched since Geim and Novosolov won the nobel prize in physics for its mechanical exfoliation from graphite. The atomically thin crystal of carbon atoms has been reported to have novel properties ... -
MAX-phase Partial Optical Properties
(2022)The optical and electrical properties of MAX-phase materials have been thoroughly studied in the past. We present here a new technique to determine and study the partial contributions to the optical properties. Following ... -
Sampling Schemes For Estimating Software Reliability
(2022)Any software system of non-trivial size cannot be easily and completely tested because the domain of all possible inputs is complex and very large. In this study, we use a technique called partition testing, in which we ... -
Comparative Investigation of LIBS Spectra and Crater Morphology During Laser Ablation of Eutectic BiSn Alloys
(2022)Laser-based methods such as pulsed laser deposition (PLD) that are used for fabricating structural and functional materials are ripe for dramatic improvement. However, because laser–material interactions are dependent on ... -
A Cubic Spline Projection Method for Computing Stationary Density Functions of Frobenius-Perron Operator
(2022)Stationary density functions of Frobenius-Perron operators have critical applications in many fields of science and engineering. Accordingly, approximating stationary density functions f* is important and the focus of this ... -
Chemical and biochemical applications of vibrational spectroscopy
(2022)Vibrational spectroscopy is a technique that probes a molecule’s vibrational modes via infrared absorption and Raman scattering, and is often used as a tool for characterization and/or functional group determination. Because ... -
Far-UV to Mid-IR Spectral Energy Distributions of Nearby Merging Galaxies
(2022)Simulations of gas-rich, major galaxy mergers predict elevated amounts of star formation (SF) and nuclear black hole growth (active galactic nuclei, or AGN). This model is supported by observations that find enhanced SF ... -
Dust-Obscured Galaxy Protocluster and Cluster Survey (DOGPACS): Identifying Large-Scale Structures 9−10 Billion Light-Years Away
(2022)Primordial density fluctuations have grown over time due to gravitational instability to form galaxies and, eventually, large-scale structures, such as clusters of galaxies. Galaxy clusters are the most massive collapsed ... -
An Analysis of the Stellar Mass Properties of Distant Galaxy Clusters From the Massive and Distant Clusters of WISE Survey (MaDCoWS)
(2022)The epoch at redshift z ∼ 1 and above is an important one for the study of the evolution of galaxy clusters, as this is the epoch where star formation in clus- ter cores in quenched. Most wide-area cluster surveys at this ... -
Exploration of the Application of Machine Learning to the Improvement of Interatomic Potentials
(2022)Current methods for atomistic simulations of material systems suffer from limitations which restrict the ability of the simulations to correctly characterize certain material behavior and physical phenomena. Small scale ... -
