PERMITTIVITY MEASUREMENT AND ANISOTROPY EVALUATION OF DIELECTRIC MATERIALS AT MILLIMETER-WAVES

Carlos A. Fernandes, Jorge R. Costa

Abstract

This paper describes the design and use of an open Fabry-Perot resonator to evaluate the degree of anisotropy of dielectric material samples at millimeter-waves. The proposed implementation not only allows identifying the orientation of the dielectric principal axes but also determining the complex permittivity values along these axes.
