Measurement of parameters of dielectric materials on characteristics of waveguide dielectric resonator

Abstract

A method of parameters measurement of dielectric materials based on resonance characteristics of a structure which consists of a cylindrical evanescent waveguide partially filled with dielectric element has been considered. Using the expressions associated with the resonance characteristics of the resonator the permittivity and the loss tangent of a dielectric for the dielectric element made of Teflon have been obtained.
