Abstract

This article presents a new technique for the characterization of low loss dielectric materials at high temperatures: the split cylinder resonator cavity. This technique allows the accurate characterization of the dimensional and electrical characteristics of the cavity and the electromagnetic properties of a dielectric material, simultaneously in one temperature cycle. To do this, the couple TE011+TE013 is used to characterize the sample and the couple TE012+TE014 is used to characterize the cavity conductivity and dimensions. Measurements of conductivity and dimensions using the couple TE012+TE014 for a loaded cavity at ambient temperature and during a thermal cycle show an agreement with the values obtained using the couple TE011+TE013 for an unloaded cavity at ambient temperature and during a thermal cycle. The characterization of an Alumina sample during a thermal cycle performed using the new technique and the traditional one shows a good agreement for the permittivities and the loss tangents.
