Sammanfattning

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.
