A new technique and results of measurements of dielectric and magnetic properties of loss dielectrics for vacuum tubes

Abstract

A technique for measuring dielectric and magnetic properties of materials by the waveguide method is proposed in which the error, associated with the presence of gaps between the sample and the waveguide wall is eliminated by comparison with the results of numerical analysis of a 3D model the dielectric characteristics of which are optimized in order to achieve the best agreement between the calculated and experimental data.
