Millimeter waves are ideally suited for sensing and diagnosing materials, devices, and processes that are broadly important to energy, environment, and national security. Thermal return reflection (TRR) techniques that detect and use thermal emission as a probe to diagnose materials and systems make possible accurate noncontact thermal analysis measurements that can resolve emissivity and temperature...
Terahertz transmission of a chalcogenide family of glasses is reported. The glasses were processed using established methods for non-oxide glasses. Transmission through the samples was measured using a THz spectrometer. The transmission and optical properties of the glasses are summarized. The results show promise of these glasses for application as THz windows.
Millimeter-wave (MMW) techniques and technologies provide robust new diagnostic tools for glass melt measurements that are addressing needs for vitrification of high level and low activity nuclear wastes in glass media at the Defense Waste Processing Facility (DWPF) in Savannah River and the Waste Treatment Plant (WTP) under construction at Hanford. Over the past seven years, we have demonstrated...
