Properties of shielded cylindrical quasi-TE/sub 0mn/-mode dielectric resonators

Comparison of the Rayleigh-Ritz method and the mode-matching method for computations of quasi-TE/sub 0mn/-mode frequencies and unloaded Q-factors of shielded dielectric resonators is presented. Rigorous bounds for the true quasi-TE/sub 0mn/-mode frequencies are assessed. Influence of various parameters on the resonant frequencies, unloaded Q-factors, and the temperature coefficients of the resonant frequency is demonstrated for many shielded dielectric resonator structures. Different approaches to unloaded Q-factor computations are discussed and numerically compared.<
