Numerical Simulation of Frequency Selective Surfaces Perforated with Arbitrarily Shaped Apertures

Abstract

We have proposed a method for the electromagnetic analysis of FSS perforated with arbitrary shaped apertures. It is based on the boundary integral equation method, mode matching technique and S- matrix method and has been implemented in a computer code. The data calculated by the code is in accordance with published ones. Furthermore, we have shown the influence of possible fabrication inaccuracies on transmission properties of the FSS.
