Modern technology uses many frequencies of electromagnetic radiation for communication, including radio waves, TV signals, microwaves and visible light. Now, a University of Utah study shows how ...
The terahertz segment of the electromagnetic spectrum exists in a sort of “twilight zone” between about 300 GHz (0.3 THz) to 3 THz (note that the upper boundary value is somewhat arbitrary, and some ...
As great as cameras that operate in the visual light spectrum are, they omit a lot of the information that can be gleaned from other wavelengths. There is also the minor issue that visibility is often ...
(Nanowerk News) The ability to control infrared and terahertz waves using magnetic or electric fields is one of the great challenges in physics that could revolutionise opto-electronics, ...

A theory from 2006 predicts that it should be possible to use graphene in a magnetic field not only to absorb terahertz and infrared light on demand but also to control the direction of the circular ...
