Abstract

This paper describes another use of the coaxial line technique for the measurement of the permittivity and permeability of magnetic and dielectric materials at elevated temperatures. The proposed modified coaxial measurement cell allows making fast and accurate broadband measurements taking advantage of a single room-temperature calibration. Measurements are performed from 50 MHz up to 20 GHz. The new coaxial cell is experimentally validated. Results for glass and ferrite samples, in the 20-300 degC temperature range, are presented
