Refractive lenses have been around forever—800 years, in fact. The basic architecture of lenses, however, may be changing. Metamaterials could revolutionize lensing systems. Conventional lenses rely on refraction at interfaces to focus…

Metamaterials, or composite synthetic materials possessing properties not seen in natural materials, are poised to take over the world. At least, that’s what a recent analysis from Lux Research seems to indicate. The metamaterial device…
