In addition to being more revealing than X-rays in some situations, T-rays do not have the cumulative possible harmful effects." Alexey Belyanin focuses his research on terahertz, otherwise known as THz or T-rays, which he says is the most under-developed and under-used part of the electromagnetic spectrum. It lies between microwave radiation and infrared (heat) radiation.
"THz radiation can penetrate through opaque dry materials. It is harmless and can be used to scan humans," Belyanin says. "Unfortunately, until recently the progress in THz technology has been hampered by a lack of suitable sources and detectors.""The highlight of our results is observations of interference of magnetoplasmons. By tiny changes in the applied magnetic field or temperature, we can make plasma waves amplify or cancel each other. This makes the whole sample either completely opaque or transparent to the incident THz radiation."
