METAMATERIALS can bend light around objects to render them near-invisible, but they absorb so much light in the process that objects cannot be flawlessly disguised. Vladimir Shalaev at Purdue University in West Lafayette, Indiana, thinks he has a solution that could help the exotic materials find their way into real-world applications. His team began with a metamaterial comprised of two layers of silver separated by insulating aluminium oxide. The horizontally layered material is perforated by vertical nanoscopic holes,
