Abstract
The effect of non-specular reflection of electromagnetic waves from a grating made of short-circuited coaxial sector waveguides is investigated. It is shown that the electric field energy of the incident wave can be transformed into the wave energy reflected in a non-specular direction. The Stokes parameters are analyzed in dependence on the length of the short-circuited coaxial sector waveguides. The possibility of converting incident linearly polarized waves into reflected circularly polarized waves is considered for the regimes of non-specular reflection of electromagnetic waves.

KEY WORDS: non-specular reflection, autocollimation mode, polarization conversion, short-circuited coaxial sector waveguide
