K BAND MICROWAVE MEASUREMENT OF THE DIELECTRIC CONSTANTS OF DRY AIR AND THREE CONSTITUENT GASES.

Abstract

The dielectric constants of dry air, nitrogen, oxygen, and carbon dioxide are determined through measurement of the resonant frequency shift in an evacuated and gas filled cavity frequency meter. The results of measurements are presented for each gas at integer frequencies from 18 through and including 26 GHz. The effects of varying the parameters of cavity resonant frequency, delta-f, temperature, and pressure are examined. The results of delta-f measurements and subsequent dielectric constants are systematically high in value when compared to previously published results. An analysis of experimental equipment performance is presented. (Author)
