Abstract: Dielectric resonators excited by higher types of azimuthal electromagnetic modes, that are whispering gallery modes, are promising to solve physical problems including studying the electrophysical parameters of substances. Disk resonators with a capillary filled with liquid and located in the whispering gallery field region are suitable to determine the permittivity of liquid. Semi-cylinder resonator located on a flat conducting mirror is of particular interest. Ensuring high accuracy and resolution in determining the permittivity of aqueous solutions under study requires a detailed study of the location of the capillary and improvement of the excitation features of the resonator. The work’s object is to develop a technique for determining the permittivity of liquid filling the capillary of semi-cylindrical dielectric resonator, and to ensure an effective interaction of the electromagnetic field of resonator whispering gallery eigenmodes with the liquid and to define the conditions for effective excitation of the resonator.
