Scalable technique for invisible metamaterials - Nanoimprinting allows researchers to bend light 10/11/2013 - 00:00 Artificial materials containing arrays of metal nanostructures can interact with light in useful and interesting ways. One of the most interesting possible uses of such ‘metamaterials’ is to bend light around objects, rendering them invisible. However, metamaterials usually only interact with light over a very narrow range of wavelengths—typically long wavelengths far beyond those visible to the human eye.
