AC-coupled substrate-integrated waveguide slot antenna in CMOS for terahertz applications
(2021-12)
Substrate integrated waveguide (SIW) technology exhibits an emerging and very promising candidate for the development of circuits and components in the millimeter-wave region. As a part of the high-frequency wireless ...
Terahertz diffuse reflectors and their effects on group delay dispersion and communication performance
(2021-12)
Engineered terahertz diffuse reflectors were created using mixtures of paint and varying amounts of aluminum powder to improve the reflectivity and scattering properties of surfaces. The performance of these reflectors is ...
Sematic understanding of large-scale outdoor web images: From emotion recognition to scene classification
(2020-12)
Facial expression recognition and scene-based image clustering are very popular topics in the fields of human-computer interaction and computer vision. Their relationship has been rarely investigated but is a very attractive ...
Statistical behavior of electromagnetic fields within aperture-coupled nested reverberant cavities
(2022-07)
Reverberation chamber (RC) theory shows that the square-magnitude of a single spatial component of a received electric field within an ideally operating chamber follows an exponential distribution. Historical experimentation ...
Reverberant electromagnetic fields within launch vehicle payload fairings
(2020-07)
A launch vehicle payload fairing scale model has been designed, fabricated, and tested at Oklahoma State University to investigate the reverberant electromagnetic fields within launch vehicle fairings. The OSU fairing model ...
Group velocity dispersion management in terahertz wireless communication channels
(2020-05)
High-fidelity models of the atmosphere from 0.1 to 1 THz based on spectroscopic databases are used to examine the effect of group velocity dispersion on ultra-wideband THz links. Previous spectroscopic characterization of ...
Open source radiation hardened standard cell library and EDA flow
(2022-05)
The development of integrated circuits (ICs) has historically had a high cost of entry due to the cost of licensing industry standard Electronic Design Automation (EDA) tools and the Intellectual Property (IP) of semiconductor ...
Design and characterization of a standard cell library for the SkyWater 130nm process
(2020-12)
This thesis discusses the design and characterization of a standard cell library for the SkyWater 130nm process. A detailed overview of the design process is examined, addressing both methodology as well as theoretical ...
Using Carry Increment Adders to Enhance Energy Savings with Spanning-Tree Adder Structures
(2019-05-01)
Hybrid adders have provided innovation in the field of digital arithmetic. These designs take the best parts of multiple implementations and improve results in terms of area, delay, or power. This work implements a 64-bit ...
Unmanned Aerial System Inspection of Instrument Landing System Radio Signals
(2019-05-01)
This study investigates the use of a unmanned aerial system (UAS) for instrument landing system (ILS) signal inspection. A model of expected equivalent isotropic receiver power was built. A 10-meter radio tower was constructed ...
