Abstract

This paper describes a technique, using rectangular or circular open-ended waveguides, for the non-destructive measurement of dielectric material properties.  The results of a detailed mathematical analysis are used to obtain a simple expression yielding the complex permittivity in terms of the measured complex reflection coefficient.  This method bring the problem within the scope of minicomputers.
