Measurement of the Electric Parameters of Materials Using the Resonator Based on a Below-Cutoff Waveguide Section

Abstract

The feasibility of measuring the complex dielectric permittivity of sheet materials using the resonator based on a below-cutoff waveguide section is considered. Measuring equations are derived with allowance for the edge resonator capacitance and incomplete filling by the sample of the region of interaction with the electric field. The electric parameters of some sheet materials have been measured in the decimeter wavelength range.
