(Phys.org)—A team of researchers with members from the University of Exeter, the University of Glasgow and QinetiQ, all in the U.K. has found a way to effectively double the resolution offered by near-field terahertz imaging. ...
From visible light to radio waves, most people are familiar with the different sections of the electromagnetic spectrum. But one wavelength is often forgotten, little understood, and, until recently, rarely studied. It's ...
