In this work, a pole matching method is presented for the analytical reconstruction, from full-wave data, of the scattering properties of frequency selective surfaces (FSS). This method allows one to synthesize the scattering response of an FSS from the identification of a few parameters, which exhibits a weak dependence with respect to the angle of incidence. This property implies that the full-wave analysis of the FSS can be performed for a limited set of incidence directions, from which the overall response can be obtained by a simple and numerically efficient algorithm. The final outcome is an analytical form for the scattering matrix which may be conveniently used in ray-tracing algorithms, based on local flat-surface approximations of curved FSS.
