Physicists at the University of St. Andrews appear to have made a breakthrough, however. They’ve created a metamaterial that really does work in the “optical range,” the scientists note in the New Journal of Physics.
Not only did Andrea Di Falco and his research partners put together a metamaterial that could bend visible light. They built it in a way that could lead to larger-scale manufacturing — and real-world applications. Not just cloaks, but lenses made out of metamaterials that can zoom to the micron level, making it possible to spot germs, chemical agents and even DNA, using basically a pair of binoculars.
“It clearly isn’t an invisibility cloak yet — but it’s the right step toward that,” Ortwin Hess, a physicist at Imperial College London, tells the BBC. “A huge step forward in very many ways.”
