High unloaded Q waveguide-dielectric resonators modes

Waveguide-dielectric resonators (WDR) with partial E-plane filling of the waveguide are considered. The eigen LM/sub mnk/ modes problem of such a WDR has been solved by the mode matching method. Theoretically and experimentally, the spectrum eigen modes dynamics dependency on the dielectric insets geometry was investigated. The calculated results are in good agreement with the experimental data.
