Abstract

A numerical model to analyze a system formed by the cascade connection of slanted strip grating plates to rotate the polarization plane of a linearly polarized wave is presented. A variant of the Generalized Scattering Matrix Theory is formulated in terms of E-type and H-type modes. These modes enable as to study three-dimensional oblique incidence upon the polarizer rotator system. A simulation program was implemented allowing the design and optimization of these systems. General criteria of design are presented, and a four-plates 60° polarizer rotator is designed in the 7-18 GHz band; a prototype was manufactured and tested. Comparison between the theoretical results and measurements are given, and a good agreement is found
