The scattering of electromagnetic waves from Frequency Selective Surface (FSS) supported by both electrically and magnetically anisotropic substrates is investigated by using Galerkin’s method in the spectral domain.The analytical procedure is introduced and Spectral Green’s function for the considered structure is formulated based on Maxwell’s equations directly.A series of FSS with different medium parameters are computed efficiently
These results reflect the influence of the electrical and magnetic anisotropy on the electromagnetic characteristics of FSS.
