Terahertz radiation, a fleeting phase of the electromagnetic spectrum, has proved difficult to manipulate with great precision. Scientists report engineering a solid-state metamaterial device capable of controlling a terahertz beam 30 times faster than a conventional optical device. The device could prove critical to new applications employing the terahertz frequency.
