Title: Devices and Applications for the millimeter wave and terahertz band

Abstrat: The millimeter wave and terahertz bands are 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.  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 millimeter wave and terahertz developments as relates to sources, communications, and imaging. Unique equipment set-ups will be presented along with demonstrations that exploit the potential these bands for near-zone communications, imaging and security.
