Whispering-gallery dielectric resonator modes have shown their usefulness in millimetre wave integrated circuits. In the paper, a method for the determination of the resonant frequencies of the whispering-gallery modes of cylindrical dielectric resonators is presented. Theoretical and experimental results are given. A comparison with other methods is also made.read more

Electromagnetic Whispering Gallery Modes in a Dielectric Rod
TL;DR: In this paper, it was shown that some of the general coupled electromagnetic modes in a large dielectric cylinder are of a whispering gallery type, which has the property that their energy is mainly confined to the region near the boundary.
