Abstract

We summarize a theoretical model for the split-cylinder resonator, based on the mode-matching method, for performing nondestructive permittivity and loss tangent measurements with the split-cylinder resonator. This new model properly takes into account the fringing electric and magnetic fields, thereby improving the measurement accuracy of the technique. Previously, the split-cylinder resonator has been used for single-frequency permittivity and loss tangent measurements using only the TE011 resonant mode. Using the higher-order TEonp modes, we demonstrate how to measure the permittivity and loss tangent of dielectric substrates over an extended frequency range. In order to verify the new split-cylinder model, we present measurements of permittivity and loss tangent from 10 to 50 GHz for fused silica substrates and compare them with measurements made with circular-cylindrical cavity, a dielectric-post resonator, and several split-post resonators.
