The Use of Higher Resonant Modes in Measuring the Dielectric Constant of Dielectric Resonators
MTT-S International Microwave Symposium Digest, 2005In the measurement procedure known as Courtney method, the dielectric constant of a cylindrical dielectric resonator is determined by measurement of the resonant frequency of the TE/sub 011/ mode. The reliability and accuracy of this method can be improved by also utilizing higher resonant modes. A procedure for identification of the modes is described,
