Notes:
The complex permittivity of various ceramics has been measured at elevated temperatures. The permittivity measurements were made using the cavity perturbation technique at a fixed frequency of 10.1 GHz. The temperature of the sample was varied from 800 to 1000 °C by independently heating the samples using a CO2 laser (up to 27 W) directed into the cavity. The samples were mounted in quartz micropipettes and illuminated through the quartz. The sample temperature was measured using an optical pyrometer. This method is valuable for measuring the microwave properties of solids that normally are exposed to microwave radiation at elevated temperatures such as high-power microwave sources, components, and windows.
