Abstract

A mode matching method for the analysis of a cylindrical dielectric resonator with arbitrarily shaped cross-section inside a waveguide is presented which allows series expansions of the fields in the region of the dielectric insert and of the waveguide with different numbers of eigenmodes. Furthermore complex modes can simply be taken into account. Resonant frequencies above the cut-off frequency of the dominant mode of the waveguide are complex due to energy radiation. The method is verified for some special cases.
