Mie Mie open resonator method for reliable permittivity measurement of loss-less ceramics in microwave frequency at high temperature

摘要

The present invention uses a frequency detected from the electromagnetic wave detection antenna unit, the electromagnetic wave detection antenna unit, which is composed of a heating unit for heating the specimen, a specimen unit having a specimen support member, an electromagnetic wave antenna for transmitting and receiving micro electromagnetic waves, and an electromagnetic wave transmissive insulating material. It includes a control unit for calculating the high temperature dielectric properties and an electromagnetic wave absorber fixed to the support plate to absorb electromagnetic waves passing through the specimen, and the control unit unit measures the Mie resonance frequency generated by the microwaves in the specimen. It relates to a high temperature dielectric constant measurement system and a high temperature dielectric constant measurement method for calculating the dielectric constant using.
