A Method for Measuring Properties of Grainy Materials using Depolarized Rayleigh-Scattering

Abstract

A new method for measuring properties of grainy materials using depolarized Rayleigh-scattering is introduced. Laboratory tests at 35 GHz with white rice and polyethene grains using a vector network analyzer and two corrugated horn antennas are presented and results are compared with theoretical results based on the first order multiple scattering theory. A low-cost measurement set-up for industrial measurements is also suggested.
