Abstract

A new method of complex dielectric constant by using TE_0ln mode in the cylindrical cavity resonator is suggested.
The specimen is of the rod type and inserted by the micrometer drive along the center of a cavity resonator.
A precise measurement formula of dielectric constant is given and accurate results are expected with the values in a formula are get from multi-points measurement.
The method may be applicable to the specimen such as powder or liquid materials.
