This paper will describe some applications of COMSOL Multiphysics to the analysis of Frequency Selective Surface (FSS) structures. Particular attention will be devoted to the possibility of designing a stealthy antenna using the FSS structure. In fact, since it possesses a dual filter concept of frequency and polarization for electromagnetic wave, the Radar Cross Section (RCS) of the antenna is reduced.
