Invisibility. How’s that for a headline? Nature reports that two engineers have devised a method to essentially cloak objects by reducing light scattering. This could have interesting applications.
Andrea Alù and Nader Engheta of the University of Pennsylvania in Philadelphia say that a ‘plasmonic cover’ could render objects “nearly invisible to an observer”. Their idea remains just a proposal at this stage, but it doesn’t obviously violate any laws of physics.
