N2 - It has been proven, based on a rigorous electromagnetic analysis, that spherical TE10p-mode Bragg-reflection resonators exhibit many times higher Q factors than corresponding cylindrical TE01delta-mode dielectric resonators, dielectric whispering-gailery-mode resonators, or empty spherical TE10p-mode cavities. Rigorous equations have been derived that allow optimally designed Q-factor and "quarter-wavelength" reflector-multilayered-spherical Bragg-reflection resonators. Experiments have been performed on three-layer spherical resonators made of single-crystal YAG and single-crystal quartz. The unloaded Q factor for the TE012 mode in these resonators was 1.04 x 10(5) at 26.26 GHz for YAG and 6.4 x 10(4) at 27.63 GHz for quartz.
