Microscopic invisibility cloak has potential for scalability

Scientists have devised an ultra-thin invisibility cloak that conforms to the shape of an object and conceals it from detection with visible light. The cloak – developed by a team from the US Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley – is very small in size at present, although it is hoped the principles behind the technology could be scaled-up.
