Abstract

The authors present a rigorous field analysis of the circular dielectric resonator embedded in an inhomogeneous medium. The analysis is by a numerical mode matching method, whereby the problems of finding the modes of the circular dielectric cylinder is cast into a conventional eigenvalue problem which could be solved rapidly on a computer. This method bypasses the need to use Hankel and Bessel functions, which could be time-consuming to evaluate. The scattering of the field off the ends of the resonator are characterized by reflection operators. The resonant frequencies of the resonator could be easily found by requiring the phase coherence of the wave after reflection off the two ends of the resonator. 11 refs.
