In the past decade scientists have been experimenting with metamaterials, artificial materials designed with periodic internal structures to give them properties not found in natural materials. Depending on their internal geometry and composition, researchers have found that they can control waves propagating through some of these materials, filtering sound or deflecting light so that an object appears “cloaked” or invisible, for instance.
