Abstract : A procedure is investigated for measuring the dielectric constant E of homogeneous and inhomogeneous substances used in th millimeter and submillimeter wave range. The determination of E is based on measuring the optical thickness of the sample or the microwave phase shift caused by the step of the investigated sample. In the experiment E was measured with the help of a phase meter operating at Lambda equals 1.6 mm. Results are presented from measuring E of substances, and the measurement errors are analyzed. It is demonstrated that the measurement of accuracy as applied to substances with E equals 2-4 is within the limits of plus or minus (0.6-1.4) percent.
