Abstract: 

WGM resonators can be used for studies of condensed matter, especially for the study of the dielectric liquids properties. However, the electromagnetic properties of the real resonator structures are not well understood. The microwave response of quasioptical radially-two-layered dielectric resonator in the form of a cylindrical ring sandwiched between two flat conducting endplates is studied. Usually real resonator has an additional layer between the leucosapphire ring and a conducting surface, that eliminates a possibility of the rigorous solution for the corresponding electromagnetic problem. The leucosapphire resonator is studied with numerical modeling methods and experimental measurements in the Ka-band. A good agreement between the experimentally measured and calculated values of frequencies and Q-factors is achieved. It is shown that the resonator allows the measurement of the complex permittivity of solutions with an error of about 3 %.
Keywords: biological liquids, complex permittivity, radially-two-layered resonator, WGM
