RELATIVE PERMITTIVITY MEASUREMENT METHOD FOR POWDER DIELECTRIC SUBSTANCE, CAVITY RESONATOR USED FOR THE SAME, AND APPLICATION DEVICE FOR IT

摘要

PROBLEM TO BE SOLVED: To provide a method for measuring a relative permittivity of powder with high precision.;SOLUTION: The relative permittivity of a mixture of powder and a liquid medium is calculated, and the relative permittivity of the mixture 18 or that of the liquid medium is assumed as the relative permittivity of the powder when the relative permittivity of the mixture 18 is equal to that of the liquid medium. In this way, even in a high frequency band above several GHz, the relative permittivity of the power can be measured with high precision.;COPYRIGHT: (C)2005,JPO&NCIPI
