New Metamaterials Can Change Properties with a Flick of a Light-Switch

Invisibility cloaks have less to do with magic than with metamaterials. These human-engineered materials have properties that don't occur in nature, allowing them to bend and manipulate light in weird ways. For example, some of these materials can channel light around an object so that it appears invisible at a certain wavelength. Now researchers have designed a new kind of metamaterial whose properties can be changed with a flick of a switch.
