  •   Terahertz technology is an emerging field that has a wide range of applications ranging from scientific applications such as astronomy, molecular specroscopy and fusion plasma diagnostics, to newly developing commercial applications including communications and imaging. The talk will focus on two recent THz projects at Virginia Diodes (VDI). 

      First, the talk will describe the development of a 1.46 THz Schottky diode receiver for use in astronomical measurements at the South Pole. The basic technology of the receiver and the system development at VDI will be described. The receiver is now being successfully used at the South Pole for observations by researchers from the University of Arizona. 

      Second, the talk will describe recent developments in THz material-measurements. A 1.1 THz vector network analyzer was used with a quasi-optical setup to characterize dielectric materials. The THz extender hardware, the calibration algorithm and measurement results using the system will be presented.
