Electrically-Triggered Microwave Filters on Coupled Modes

In this work, the structure of the waveguide-dielectric resonator with the combined ferrite-dielectric sandwich sample, on the basis of the design of electrically-tuned selective devices on microwaves, have been experimentally investigated. It was established that the effect of triggered coupling between the lowest types of modes exists not only at the presence of degeneration of the given mode types, but also at the channel selectivity on significant magnitude. The technique of the choice of electrically-tunable filters (ETFs) optimized operating mode resulted at transversal and longitudinal magnetizing mode of the ferrite sample of the filter.
