New Terahertz Chips For New Devices
2012-12-10 19:11:57

Lee Rannals for redOrbit.com — Your Universe Online A new set of microchips designed at the California Institute of Technology pave the way for a new generation of devices. The chips created by the Caltech engineers generate and radiate high-frequency electromagnetic waves known as terahertz (THz). These waves fall between microwaves and far-infrared radiation and are able to penetrate materials without damaging them, unlike X-rays. The new microchips could be incorporated...
