Abstract:

In this article, a new method that is based on a combination of electromagnetic topology and mode matching is proposed for the analysis of electromagnetic field coupling. The proposed method can accurately solve the electromagnetic field coupling in a complex system with a short computation time and reduced memory. A wire within an aperture-backed cavity model was analyzed, and the electric field intensity in the cavity and the induced surface current on the wire were computed. The results were compared with finite difference time domain results and confirmed the electromagnetic field coupling is influenced by the geometry of the enclosure.

Keywords: aperture backed cavity; electromagnetic field coupling; electromagnetic topology; mode matching
