It's not everyday that researchers make some progress towards terahertz computing, but a team from the University of Utah led by Ajay Nahata appear to have done just that, with them announcing that they've "taken a first step to making circuits that can harness or guide terahertz radiation." That, they say, could allow for the development of "superfast circuits, computers and communications," and "in a minimum of 10 years," no less. The key to this latest development, it seems, is the use of some sheets of stainless steel foil perforated with tiny holes, which can be arranged in different patterns to effectively form "wires" to carry the terahertz radiation. In their tests, the researchers were able to do so at a level of 300Ghz (or 0.3 terahertz), although they admit that they still have a long way to go, saying that "all we've done is made the wires" for terahertz circuits, and adding that there still needs to be devices like switches, transistors and modulators developed at terahertz frequencies in order for anything practical to become possible.
