An emerging technology involving tiny particles that absorb light and turn it into localized heat sources shows great promise in several fields, including medicine. For example, photothermal... Read more
Together with their colleagues from Germany and the Netherlands, scientists at the Moscow Institute of Physics and Technology (MIPT) have found a way to significantly improve computer perfor... Read more
Terahertz waves, operating at a much higher frequency than microwaves, could one day be used to carry data many times faster than today’s cellular and Wi-Fi networks. More work needs to be d... Read more
Tunable radiation source that reaches coveted THz region of spectrum could be used for medical imaging or security applications Terahertz radiation, the no-man’s land of the electromag... Read more
Researchers created a compact terahertz radiation source that operates at room temperature We are all familiar with the hassles that accompany air travel. We shuffle through long lines, remo... Read more
New research at the University of Maryland could lead to a generation of light detectors that can see below the surface of bodies, walls, and other objects. Using the special properties of g... Read more
Imagine a technology that could allow us to see through opaque surfaces without exposure to harmful x-rays, that could give us the ability to detect harmful chemicals and bio-agents from a s... Read more
A device that essentially listens for light waves could help open up the last frontier of the electromagnetic spectrum—the terahertz range. So-called T-rays, which are light waves too long f... Read more
Using an inexpensive inkjet printer, University of Utah electrical engineers produced microscopic structures that use light in metals to carry information. This new technique, which controls... Read more
Standing in a full-body scanner at an airport isn’t fun, and the process adds time and stress to a journey. It also raises privacy concerns. Researchers now report in ACS’ The Journal of Phy... Read more
The THz generation can be tailored simply by tuning the size of the meta-atoms in the metamaterial Scientists at the U.S. Department of Energy’s Ames Laboratory have demonstrated broad... Read more
“This area is possibly the last range of the electromagnetic spectrum that is yet to be developed and exploited” Researchers at the Universidad Carlos III of Madrid (UC3M) and the firm Luz W... Read more
