Results of experimental study and theoretical analysis of spectral characteristics of "whispering gallery" HE mode waves are presented for a disc quasi-optical dielectric resonator (QDR) with liquid-filled capillary as a heterogeneity. The character of QDR eigenfrequency dependence with different liquids is different with capillary diameter change. The(More)
A semi-cylindrical dielectric resonator with capillary non-uniformity was studied. The characteristic equation was obtained to determine eigen frequencies of such resonator structure. The expressions for determination of electromagnetic field components for axial-homogeneous eigen oscillations of resonator are given. It is shown the non-uniformity results(More)
