Designing metamaterials Sandia National Laboratories has developed an inverse-design software technology that automates the design of optical metamaterials. Metamaterials are artificial materials containing arrays of metal nanostructures or mega-atoms. Some metamaterials are able to bend light around objects, rendering them invisible. But they only interact with light over a very narrow ran... » read more
