New Devices and Applications for the Sub-Terahertz and Terahertz Bands

The terahertz band (0.3 -10 THz) is associated with several attractive applications, including spectroscopic identification, security, non-destructive imaging and wideband proximity wireless communications. However, exploitation of the terahertz band is still at its infancy. This is due to the lack of portable sources, transceivers and low cost portable imaging devices. Recently, Ohio State acquired several sub-terahertz and terahertz equipment for signal generation, spectroscopy, imaging, testing and evaluation of components and systems. In this presentation, we will review several new developments in terahertz as relates to sources, communications, and imaging. Unique equipment set-ups will be presented along with demonstrations that exploit the potential of terahertz for near-zone communications, imaging and security.
