A team of researchers at the University of Texas at Dallas, led by Professor of Electrical Engineering Dr. Kenneth O, have created a technology that could allow future smartphones and cameras to see through walls. The research brought together two scientific advances, one that involves tapping into an unused range in the electromagnetic spectrum and another that deals with a new microchip technology. The terahertz band of the spectrum needed for this technology to function has not been accessible for most consumer devices, however the team is looking to change that.
“Weâve created approaches that open a previously untapped portion of the electromagnetic spectrum for consumer use and life-saving medical applications,â said Dr. O. “The terahertz range is full of unlimited potential that could benefit us all.” Thanks to a new approach, images can be created in the terahertz band without using several lenses inside a device, instead requiring a single CMOS technology censor.
“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.â Due to privacy concerns, however, Dr. O and his team are focused on uses in the distance range of less than four inches.
The technology could be used for finding studs in walls, authenticating important documents and detecting counterfeit money. “There are all kinds of things you could be able to do that we just havenât yet thought about,” Dr. O concluded.

Comments Off on Terahertz bandwidth: the key to 1,000x faster smartphones, laptops and pipe dreams
Researchers at the University of Pittsburgh announced that they have discovered a means of wirelessly transmitting data thousands of times faster than current standards, PCMag reported on Wednesday. The team is led by Hrvoje Petek, a physics and chemistry professor at the university, who has theoretically found a way to transmit data between devices in the terahertz frequency. Petek’s discovery of “a physical basis for terahertz bandwidth” could potentially be used to leverage the “portion of the electromagnetic spectrum between infrared and microwave light” and transmit data at rates 1,000 times faster than today’s wireless standards, which are limited to the gigahertz frequency. “The ability to modulate light with such a bandwidth could increase the amount of information carried by more than 1,000 times when compared to the volume carried with today’s technologies,” Petek said. “Needless to say, this has been a long-awaited discovery in the field.”
