Vector scattering of arbitrarily directed incident plane waves by frequency selective surfaces
Abstract
The scattered fields for plane waves of arbitrary polarization arriving from an arbitrary direction are analytically determined. The scattering coefficients for principal-plane incidence are evaluated from the equivalent circuits and used in conjunction with the analytical method to obtain the coefficients for any incidence plane. The transmission line equivalent circuit representations of strip gratings, when a plane wave is incident in a principal plane, are used to obtain the transmission coefficients in arbitrary incidence. The application of this analysis is also demonstrated for a planar array of square loops set in a square lattice.
