Method of measuring relative dielectric constant of dielectric substance of powders, cavity resonator used in the same, and application apparatus |
摘要 |
A relative dielectric constant of a mixed substance consisting of powders and a liquid medium is calculated, and then the relative dielectric constant of the mixed substance or a relative dielectric constant of the liquid medium is calculated as a relative dielectric constant of the powders where the relative dielectric constant of the mixed substance becomes equal to a relative dielectric constant of the liquid medium. Therefore, the relative dielectric constant of the powders can be measured with high precision even in a high-frequency band in excess of several GHz.
