DIELECTRIC PROPERTIES OF STEATITES AT MICROWAVE AND RADIO FREQUENCIES BEFORE AND AFTER IRRADIATION

摘要

The changes in the dielectric properties of steatite ceramic before and after irradiation were studied. The characteristic vibrational frequency ω_0 affects the change in the properties of the ceramic, which is important for devices operating in the presence of radiation. It was found that the permittivity of ceramic increased after irradiation. The structure of the material and the sintering temperature of the ceramic determine the relaxation region of the material.
