WASHINGTON – Top scientists in Israel are on the verge of a revolutionary breakthrough, creating a cloak that can render a person invisible. In their real-world quest for invisibility, scientists at Ben-Gurion University have developed a device that scatters light away from an object so it cannot be detected, making the object invisible to the eye. Physicists developed the method for concealing objects based on the study of “metamaterials,” which focuses on exploiting and controlling light by examining how it interacts with objects. Those arrays of minuscule components bend, scatter, transmit or otherwise shape electromagnetic radiation in ways that no...
