Scientists have developed a new way to create electromagnetic Terahertz (THz) waves or T-rays - the technology behind full-body security scanners. The researchers behind the study, published recently in the journal Nature Photonics, say their new stronger and more efficient continuous wave T-rays could be used to make better medical scanning gadgets and may one day lead to innovations similar to the 'tricorder' scanner used in Star Trek.

Swissto12 -- an EPFL spin-off -- could help boost the performance of detection systems and create new antennas for mobile telephony and on-board satellite systems thanks to an innovative transmission system that takes advantage of a previously under-utilized wavelength: the terahertz.

Researchers at Northwestern University have created a new kind of cloaking material that can render objects invisible in the terahertz range.

Invisibility appears to be the next possible advance in the use of Terahertz radiation in medicine, security, and communications.
