Breakthrough metasurface materials tech unleashes enhanced control for advanced telecommunications and beyond

Cities can be obstacle courses for communications signals. A radio signal must travel from a cell phone to a router to a cell tower, and onward to its recipient—all while bouncing between walls, buildings and other structures. When it hits an obstacle, the radio wave gets scattered, diminishing the signal. This in turn reduces the bandwidth. At the same time, the signal must compete with the bandwidth needs of numerous other devices in the area. All this reduces the amount of information the signal can communicate.
