Abstract

The main electrodynamic properties of two-layered quasi-optical sapphire resonator in a form of cylindrical ring, an inner hole in which was filled with liquid or (super)conductor were studied. The resonator war excited on whispering gallery modes in Ka-band and its microwave characteristics were investigated to obtain parameters of condensed matter under test. The calculation results are obtained using CST Microwave Studio. The analysis of experimental data and results of numerical calculations show that developed resonator is promising for high-sensitive microwave characterization of different substances with both extremely high (e.g. lossy liquids) and extremely low (e.g. superconductors) losses. The experimental results were obtained in Ka-band.
