RESUMO

The characteristic equation for complex frequencies of a two-layered (along radius) quasi-optical dielectric resonator with conducting endplates has been obtained. In a particular case of an inner hole in the dielectric cylinder, the experimental dependences of the resonator eigen frequencies on the radius of the hole are given for the eight-millimeter wave band. The frequency spectrum evolution of "whispering gallery" waves in the spectrum of a dielectric ring-waveguide is shown. A good coincidence of theoretical and experimental data is obtained for EH- and HE-oscillations in a teflon resonator.
