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 ...

Light-powered 3-D printer creates terahertz lens

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 ...

Terahertz technology reaches industrial maturity

Terahertz is a new technology in which nondestructive testing of components and surfaces is possible. Until now, these devices and, in particular, the sensor heads have been expensive and unwieldy. Researchers at Fraunhofer ...

Graphene is both transparent and opaque to radiation

A microchip that filters out unwanted radiation with the help of graphene has been developed by scientists from the EPFL and tested by researchers of the University of Geneva (UNIGE). The invention could be used in future ...

Researchers develop new lens for terahertz radiation

Terahertz radiation is a relatively unexplored slice of the electromagnetic spectrum, but it holds the promise of countless new imaging applications as well as wireless communication networks with extremely high bandwidth. ...

Researchers control properties of light using nanostructures

A theoretical study based on computational simulations conducted by the UPV/EHU's Nano-bio Spectroscopy Research Group in collaboration with the Japanese research centre AIST has shown that the intensity of ultraviolet light ...
