In this paper, we present the space-domain integral- equation method for the analysis of frequency selective surfaces (FSS), consisting of an array of periodic metallic patches or a metal screens perforated periodically with arbitrarily shaped apertures. The computation of the spatial domain Green's function is accelerated by the Ewald transformation. The geometric model is simplifled by the lattice symmetry, so that the unknowns are greatly reduced. Time of fllling MOM matrix and solving linear system is dramatically reduced. Our technique shows much higher e-ciency when compared with the available commercial software and the existing methods published.
