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.
