PopSci, Engadget and many others talk about work by Kenneth O, professor of EE at UT Dallas and director of the Texas Analog Center of Excellence(TxACE) at University of Texas at Dallas. "We’ve created approaches that open a previously untapped portion of the electromagnetic spectrum for consumer use and life-saving medical applications," said Dr. Kenneth O.
"CMOS is affordable and can be used to make lots of chips," Dr. O said. "The combination of CMOS and terahertz means you could put this chip and receiver on the back of a cellphone, turning it into a device carried in your pocket that can see through objects." Due to privacy concerns, Dr. O and his team are focused on uses in the distance range of less than four inches.
