Ultra-fast light-shaping technology could be 'game-changer' for future imaging

Scientists have developed a new type of "virtual" metasurface—capable of controlling light in ways traditional lenses and optics can't—which they say is superior to the current approach, which relies on ultrathin engineered materials. The Nottingham Trent University team says the work will help fully optimize metasurface potential for a range of real-world applications and paves the way for a move from physical to virtual platforms in nanotechnology.
