Coupling of Non-Axially Symmetric Hybrid Modes in Dielectric Resonators

Abstract

A method for the rigorous calculation of the coupling coefficient between dielectric resonators excited in non-axially symmetric hybrid modes is developed. A simplified model is derived which allows approximate accurate calculations of coupling, without solving the detailed boundary value problem. Experimental measurements of the coupling between the two lowest hybrid modes were performed to verify the models, and are found to be in excellent agreement with the calculations.
