Polarization Transformation under the Nonspecular Reflection of Electromagnetic Waves from a Two-Dimensional Periodic Grating of Rectangular Short-Circuited Waveguides

Abstract

Polarization transformation under the nonspecular reflection of electromagnetic waves from a two-element two-dimensional periodic grating of rectangular short-circuited waveguides is shown possible. The conditions for transformation of linearly polarized waves into those cross- or circular polarized in autocollimating and “rectangular” reflection modes are found.
