Propagators and Scattering of Electromagnetic Waves in Planar Bianisotropic Slabs - An Application to Frequency Selective Structures
- 2004

Journal article (peer-reviewed)abstract
- Scattering by planar geometries with plane metal inclusions are analysed. The metal inclusions can be of arbitrary shape,and the material of the supporting slabs can be any linear (bianisotropic) material. We employ the method of propagators to find the solution of the scattering problem. The method has certain similarities with a vector generalisation of the transmission line theory. A general relation between the electric fields and the surface current densities on the metal inclusions and the exciting fields is found. Special attention is paid to the case of a periodic metal pattern (frequency selective structures,FSS). The method is illustrated by a series of numerical computations.

Scattering from a frequency selective surface supported by a bianisotropic substrate
- 2002

In: Progress in Electromagnetics Research-Pier. - 1070-4698. ; PIER 35, s. 83-114
-
Journal article (peer-reviewed)abstract
- 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.
