Analysis of frequency selective surfaces with ferrite substrates
Title
Analysis of frequency selective surfaces with ferrite substrates.
Creator
Liu, Youcheng, Christodoulou, Christos, Engineering
Abstract / Description
University of Central Florida College of Engineering Thesis; Frequency selective surfaces (FSS) have numerous applications in several microwave and optical systems. In this work, instead of traditional dielectric substrates, ferrite substrates are used under different dc bias conditions.

Abstract / Description
University of Central Florida College of Engineering Thesis; The focusing properties of chirped diffraction gratings have long been studied and often used in applications at optical frequencies. Chirped metallic gratings of this type have also been studied theoretically at microwave frequencies, but no attempt has been made to experimentally examine or utilize the focusing properties of these structures at microwave frequencies.

Chirped metallic gratings of this type have also been studied theoretically at microwave frequencies, but no attempt has been made to experimentally examine or utilize the focusing properties of these structures at microwave frequencies. This thesis presents an experimental analysis of the focusing properties of chirped metallic gratings. These gratings are designed to focus electromagnetic energy at a predetermined position by varying strip width and spacing as a function of position. The diffraction gratings are characterized, and experimentally measured results are compared to theoretical data.
