Optical wireless communication (OWC) stands out as one of the most promising
technologies in the sixth-generation (6G) mobile networks. The establishment of high-quality …

An electronically reconfigurable dual-band reflectarray antenna is presented in this paper.
The tunable unit cell, a ring loaded square patch with a single varactor diode connected …

This paper presents an alternate microwave imaging system that greatly reduces design and
operation complexities compared to traditional imaging systems. At the heart of this novel …

Filtered backpropagation (FBPP) is a well-known technique used in Diffraction Tomography
(DT). For accurate reconstruction of a complex-valued image using FBPP, full 360 angular …

Diffraction tomography (DT) from limited projection data has been an active research topic
for over three decades. The interest has been steadily fueled due to its application in …

Here, a microwave measurement strategy is proposed to decrease the number of antennas
used in the measurement system for through-the-wall microwave imaging applications. To …

Abstract Theory, experiment, and computation are the three paradigms for scientific
discoveries. This dissertation includes work in all three areas. The first part is dedicated to …

Microwave testing of dielectric materials has recently become an increasingly important
field. Dielectric materials such as composites are preferred over metallic counterparts, due to …

In this dissertation a new wideband circular HIS is proposed. The circular periodicity made it
possible to illuminate the surface with a cylindrical TEMz wave and; a novel technique is …

Микроволновой НК диэлектрических материалов в последнее время становится всё
более востребованным. Диэлектрические композитные материалы предпочтительны …
