Loss Mechanisms In Dielectric Loaded Resonators

摘要

Analysis is presented of resonators consisting of a section of a dielectric loaded waveguide shorted at both ends. The analysis includes resonant frequency calculation, mode charts and unloaded Q computation. Numerical results are presented for the unloaded Q's of various modes, as a function of the resonator parameters. Effects of losses in different parts of the resonator wall on the unloaded Q are discussed, and methods of improving these Q's are explored.
