      다국어 초록 (Multilingual Abstract)

      Constituent structures of 1/2 or 1/4 parts of dielectric resonators (DRs) reflected in the metallic mirrors were studied. The structures were studied by electrodynamics in order to optimize constituent devices. By the controlling of air slot between parts of DRs and mirrors (which were waveguide walls), it is possible to change a central frequency of the constituent structure or its attenuation frequency characteristic. Experimentally examined resonant devices show a high quality factor and allow to fast change of their resonant frequency (up to 20-25%). Based on these concepts, bandpass and bandstop frequency tuned filters were realized. Electronic adjustment of studied devices is possible as well, if the air slot of constituent resonant structure is shunted by the PIN diode.
