Material characterization in partially filled waveguides using inverse scattering and multiple sample orientations
Abstract in UndeterminedWe present a method aimed at reducing uncertainties and instabilities when characterizing materials in waveguide setups. The method is based on measuring the S parameters for three different orientations of a rectangular sample block in a rectangular waveguide. The corresponding geometries are modeled in a commercial full-wave simulation program, taking any material paramet
