The SIE-MoM analysis of dielectric bodies embedded in a shielded stratified medium

This paper describes formulation and application of the surface integral equation (SIE) approach to the problem of scattering by material bodies inside waveguides and cavities filled with a stratified medium. The formulation in based on the full dyadic electric and magnetic waveguide Green functions both for the external and internal equivalent problems. To the best authors knowledge such an approach has never been presented in the open literature. In this paper we show numerical and experimental validation of the proposed formulation and a comparison of its performance with the Finite Integration Technique (FIT) implemented in commercial software.
