University of Utah researchers have developed a way to control terahertz radiation with better accuracy, potentially allowing mobile devices to take advantage of new frequencies that haven't been suitable for wireless communications in the past. According to Ajay Nahata, research leader and professor of electrical and computer engineering, routers and receivers that use terahertz radiation, which ranges from about 100 gigahertz to 10 terahertz, could transmit more data to speed up wireless Internet links a thousand times. Nahata's team built a perforated stainless steel film that has the ability to selectively allow certain terahertz frequencies to pass through and cancel out other signals. Article
