Metamaterials Pave Way for Superlens
ITHACA, N.Y., Nov. 11, 2011 — Casting tiny, oddly shaped metal structures inside plastic molds could give a boost to creating metamaterials for making “superlenses” that can image proteins, viruses and DNA.
Metamaterials, which offer new ways to manipulate light via negative refractive indices, typically are made with common deposition and lithography techniques. The limitation has been that techniques such as electron-beam lithography or atomic sputtering can create materials in thin layers only. However,...
