Abstract :
The dispersion equation for complex frequencies of a radially-three-layer cylindrical dielectric resonator with perfect conductive end walls was obtained. The studying of influence of a middle layer, filled different substances, on a frequency and quality factor of resonator was carried out. Spectral and energy characteristics of a resonator with a whispering gallery oscillation were studied at different thickness of middle layer and its position along the radius. Different nature of behavior of an eigen frequency of resonator was obtained filling a middle layer by liquid with both small and large losses.
