Numerical techniques for analyzing finite planar frequency selective surface with dielectric substrate

Abstract

A full-wave analysis for the transmission characteristic of finite planar frequency selective surface (FSS) is presented using the method of moment (MoM) with the layered medium Green's functions. A fast numerical approach, the multilevel UV method, is employed to speed up the MoM solution. Finally, numerical results show the good performance of the approach, and its accuracy is verified by the agreement between our computed results and that generated by Designer.
