Amorphous hydrogenated boron carbide for solid-state direct-conversion thermal neutron detection
(2021)Amorphous hydrogenated boron carbide (a-BC:H) is one of a very limited number of neutron-sensitive materials. It has been studied over the last three decades for solid-state thermal neutron detection due to its high ... -
The Bulk and Interfacial Electronic and Chemical Structure of Amorphous Hydrogenated Boron Carbide
(2013)The chemical and electronic structure, as related to the surface, interface and bulk of amorphous hydrogenated boron carbide (a-BxC:Hy), is of interest in neutron detection and microelectronics. This dissertation investigates ... -
Design of Instrumentation and Methodologies for Determination of Free Neutron Characteristics
(University of Missouri -- Kansas City, 2017)Measuring neutron source‐dependent free neutron properties over a large neutron energy range, with human‐portable instrumentation, continues to push the frontier of neutron detection instrumentation design and analysis ... -
Ferroelectric System Dynamics and the Properties of Ferroelectric / Two-Dimensional Electron Gas Heterostructures: a Ginzburg–Landau Study
(University of Missouri -- Kansas City, 2017)Understanding the electronic response of materials to applied electric fields is an outstanding goal in solid-state theory. One aspect of this goal is to accurately predict the electric polarization of certain materials ... -
Frequency and Field Strength Materials Characterization with Complementary Split-ring Resonators, Coplanar Waveguides, and the Virtual Ground Method
(University of Missouri -- Kansas City, 2019)In the radiofrequency bands, measuring the power-dependent complex permittivity and permeability of materials that undergo metal–insulator transitions is a significant challenge which is important for defense and ... -
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 ... -
Modeling and Design of a Silicon-Based High-Pressure 3HE Replacement Neutron Detector
(University of Missouri–Kansas City, 2015)3He has stood as a major isotope used for neutron detection for many years. Due to national concerns of a possible 3He shortage, significant effort has been put forth, in the form of 3He alternative research, to push the ... -
Neutron Response Vectorization and Optimization of Moderating Neutron Spectrometers for Active Interrogation
(University of Missouri–Kansas City, 2015)The detection of special nuclear material (SNM) is no trivial task; the low activity of isotopes such as 235U and the ease of shielding make their passive detection virtually impossible in the maritime environment. Active ... -
Photoemission Spectroscopy Studies of New Topological Insulator Materials
(2015-08-04)As the size of a solid shrinks, the ratio of surface area to bulk volume grows and surface effects become more important. In a world where technologies advance with the shrinking size of electronic devices, one phase of ... -
Pulse Generation, Shaping, and Optimization Solutions for Solid-State-Switch-Enabled High-Power Microwave Generation Systems
(2022)This work presents an ensemble of solid-state pulse power solutions and approaches for the compact and light-weight ultrawideband high-power microwave (HPM) application space. The semiconductor-based foundation overcomes ... -
RF coupling to realistic wire systems in complex environments
(2021)With the continuous emergence of new wireless technologies, the possibility of unintentional electromagnetic interference (EMI) increases significantly. EMI coupling pathways to any Device Under Test (DUT) can be classified ... -
Uranium Oxides for Solid-State Direct-Conversion Neutron Detection
(2020)This study is focused on studying the potential of uranium oxides as solid-state direct-conversion neutron detectors. By modeling uranium oxides as neutron detectors, we found that thick detectors with suitable uranium ... -
Wideband high-power transmission line pulse transformers
(2021)Geometric transformers are often used in radar and communications systems to transition between signal driving and radiating elements that terminate in significantly different geometries with unity input/output impedance. ...
