  • Abstract
    In the measurement of the dielectric constant of gases or changes in the dielectric constant of solids and liquids at centimeter wavelengths, the need arises for the accurate determination of small changes in the resonance frequency of a cavity resonator. A sensitive instrument designed to measure and record such changes in frequency has been developed which is adaptable to very low loss materials.
