Kildishev Metasurfaces (image) Purdue University Caption This schematic view of a nanoantenna array (A), at left, is an example of new plasmonic metasurfaces that are promising for various advances, including a possible "hyperlens" that could make optical microscopes 10 times more powerful. At right (B) is a "hyperbolic metasurface," a tiny metallic grating for enhancing "quantum emitters," which could make possible future quantum information systems far more powerful than today's computers.
