Sammanfattning

Scattering by planar geometries with plane metal inclusions are analyzed. 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 generalization 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 are 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.
