Tuning terahertz transmission

The ability to manipulate light on a subwavelength-scale could lead to a revolution in photonic devices such as antennas, solar panels, and even cloaking devices. Nanotechnology advances have made this possible through the ...

The fingerprints of molecules in space

Physicists at the University of Innsbruck are on the hunt for nitrogen-containing molecules in space. Using terahertz spectroscopy, they directly measured two spectral lines for one particular molecule for the first time. ...

Speedy terahertz-based system could detect explosives

Terahertz spectroscopy, which uses the band of electromagnetic radiation between microwaves and infrared light, is a promising security technology because it can extract the spectroscopic "fingerprints" of a wide range of ...

New insights into the supercritical state of water

Using molecular dynamics simulations, researchers have analysed the properties of supercritical water. The researchers showed which structure of the hydrogen bond network is formed in different supercritical states and also ...
