TLDR
In this paper, a noncontact microwave measurement technique to measure the change in conductivity profile of glass mixture with temperature (30-700 √ C) is presented. Butler et al. used a corrugated horn to identify the relative change in material conductivity with respect to temperature.Abstract:
A non-contact microwave measurement technique to measure the change in conductivity profile of glass mixture with temperature $(30-700^{\circ}\mathrm{C})$ is presented here. Mono static radio detection and ranging (RADAR) signals from the glass melts recorded using a corrugated horn are processed to identify the relative change in material conductivity with respect to temperature.read more

TL;DR: In this paper, a non-contact microwave sensor is presented for in situ process monitoring of nuclear waste glass melts inside a cold crucible induction melting (CCIM) furnace, and the level and thermal steady state of the molten glass inside a 1400°C CCIM furnace were measured during 6-hour long vitrification process using a corrugated horn antenna operating over 20-24 GHz designed for high temperature measurement.
