Electron concentration-dependent optical properties of indium arsenide
(2023-05-12)
Since humans began using mirrors to reflect light, its control has been a subject of research for thousands of years. With the use of Maxwell’s equations, we came to realize that controlling light is primarily achieved ...
Theory, Design, and Fabrication of Frequency Agile Filtennas
(2020-07-30)
With the development of modern wireless systems, the spectral environment has become increasingly crowded. This has spawned a strong interest in frequency, bandwidth, and pattern reconfigurable RF front ends, which can ...
Reconfigurable filter design using liquid metal actuation
(2021-05-14)
The emergence of technologies such as 5G, IoT, automotive radar, wireless power transfer, broadband satellite internet, and more has increased the number of devices operating and transmitting in the radio frequency (RF) ...
Quasi-Omnidirectional Broadband Anti-Reflective Surface of Multi-Level Sub-Wavelength Structures
(2020-12-18)
The demand to remove reflections from surfaces has been a topic of interest for many decades. Accordingly, many methods and techniques have been exploited to achieve the optimum design, which is to impart no reflections ...
Using Inexpensive Software-Defined Radios as GPS Receivers in a Ground-Based Augmentation System
(2022-12-16)
Ground Based Augmentation Systems (GBAS) are used to augment Global Positioning Systems (GPS) signals to make the position solutions significantly more accurate and precise. The systems have been studied and demonstrated ...
Analysis of dynamics of road weather information system data
(2023-12)
Road and Weather Information System consists of a network of roadside Environmental Sensor Stations (EES) collecting meteorological data. Equipped with a variety of sensors, these stations gather data including ambient ...
A Real Time Ground Based Augmentation System Implemented with LabVIEW Software
(2022-12-16)
This thesis develops and implements a real time Ground Based Augmentation System (GBAS) in the LabVIEW environment incorporating the Local Monitor (LM) from the Closed-Loop GBAS (CL-GBAS) concept. GBAS, also referred to ...
Intraoperative Virtual Surgical Planning Through Medical Mixed Reality
(2021)
The mission is to augment every surgery. Compared to a pilot flying a plane or even a regular google-map user on his way to work/home, surgeons today have their instruments clustered behind them hanging in the wall. The ...
Spatially-Temporally Resolved Sampling System for Carbon Dioxide Concentration in The Atmospheric Boundary Layer: A Low-Cost UAS Approach
(2020-05-08)
Given the consensus around the importance of atmospheric carbon dioxide (CO2) to human life on earth, its monitoring has grown significantly in the past 60 years. However, there is still a knowledge gap regarding the ...
Design and Optimization of Broadband Matching Networks for Widely Steerable Phased Array Radar Systems
(2022-05-13)
The use of phased arrays have become prevalent in radar systems for military and weather applications due to their planar configuration and ability of electronic steering. However, mutual coupling between surrounding antenna ...
