Scattering by FSS on anisotropic substrate for TE and TM excitation

The scattering of electromagnetic waves from frequency-selective surfaces (FSS) composed of rectangular conducting patches mounted on uniaxial dielectric anisotropic substrate is investigated by using a full-wave analysis. The moment method is used in combination with the spectral-domain immittance approach to determine reflection and transmission coefficients of the FSS structure as function of the geometry parameters and dielectric anisotropy. The analysis provides very accurate results compared to those presented by others and to those obtained by measurements.
