Wires that carry terahertz electromagnetic radiation could carry 1,000-GHz signals. That's 20 times faster than the speed of the world's fastest microprocessor, which IBM Corp. announced last week.
Until now, the terahertz gap has prevented circuitry from rising much above 60 GHz—the speed of next-generation wide personal-area networks, or WPANs. Now, researchers at the University of Utah have demonstrated a method of building wires that act as terahertz-caliber waveguides atop stainless-steel foil by using lines of micron-scale perforations. The technique was shown to transmit, bend, split and combine terahertz radiation at 0.3 THz (300 GHz) but could be extended up to 10 THz, according to electrical-engineering professor Ajay Nahata at the university.Text: http://www.eetimes.com/showArticle.jhtml?articleID=207401260
