Scattering from a frequency selective surface supported by a bianisotropic substrate

Summary, in English

In this paper a method for the analysis of a frequency selective surface (FSS)

supported by a bianisotropic substrate is presented. The frequency selective

structure is a thin metallic pattern — the actual FSS — on a plane supporting

substrate. Integral representations of the fields in combination with the

method of moments carried out in the spatial Fourier domain are shown to

be a fruitful way of analyzing the problem with a complex substrate. This

approach results in a very general formulation in which the supporting substrate

can have arbitrary bianisotropic properties. The bianisotropic slab

can be homogeneous, stratified, or it can have continuously varying material

parameter as a function of depth. The analysis presented in this paper is

illustrated in a series of numerical examples. Results for isotropic, anisotropic

and bianisotropic substrates are given.
