Polarization Rotator - Analysis and Design

Abstract

This paper presents a new analysis of a polarizer composed of N sections of frequency selective surfaces (FSS). Each FSS is composed of periodic array of conducting wires. The structure is analyzed with the use of the exact full-wave theory based on the the mode-matching method, and also an efficient numerical technique based on the T- matrix approach and the lattice sums is utilized to investigate the FSSs.
