FREQUENCY-SELECTIVE SURFACES ON ISOTROPIC CHIRAL SLABS

A full-wave analysis for the problem of scattering by a new frequency selective surface (FSS), named Chiro-FSS, is presented. The Chiro-FSS consists of a two dimensional infinite periodic array of thin, perfect ly conducting elements printed on an isotropic chiral substrate. The a nalysis is based on the Modal Analysis and Method of Moments combined with the Floquet Theorem. Numerical results of reflection and transmis sion characteristics of the Chiro-FSSs with cross dipoles, circular ri ngs and rectangular plates are presented for normal incidence.
