A System for Rapid Measurements of RF and Microwave Properties Up to 1400°C. Part 2: Description of Apparatus, Data Collection Techniques and Measurements on Selected Materials.

A system has been developed, based on the cavity frequency shift technique, for doing rapid scoping measurements of the complex permittivity and scalar permeability from 50 to 2450 MHz andfrom-160°C to +1400°C. The measurement system, including multimode rf cavities, is described, and some measurements on a selection of materials are presented to demonstrate the use of the system.
