New Terahertz System Simpler, Clearer
EVANSTON, Ill., June 6, 2014 — Biosensing, space research and the ability to see through opaque surfaces without x-rays are all enabled by terahertz radiation. However, such systems have long been elusive. A team from Northwestern University has produced terahertz radiation in a simplified system, making it easier to harness the power of such waves. Existing terahertz systems are expensive and large, with numerous components that require complex technologies, such as vacuum electronics, external pump lasers and
