Abstract
In this paper we describe a new method for measuring the dielectric and absorption constants of materials at millimeter frequencies. This new method is called digital spectrometry and rests on a little known property of Fresnel's equations for reflection at 45° and the recent appearance of highly accurate digital voltmeters. The fundamental equations for digital spectrometry are presented and in the final section of the paper the experimental configuration is described.
