Cloaking, sooner than you might think

Researchers at Birck Nanotechnology Center at Purdue's Discovery Park have proposed a cylindrical cloaking device which operates at optical frequencies.

Abstract from Nature Photonics.

Vladimir Shalaev, Purdue's Robert and Anne Burnett Professor of Electrical and Computer Engineering:

“Creating the tiny needles would require the same sort of equipment already used to fabricate nanotech devices. The needles in the theoretical design are about as wide as 10 nanometers, or billionths of a meter, and as long as hundreds of nanometers. They would be arranged in layers emanating from a central spoke in a cylindrical shape. A single nanometer is roughly the size of 20 hydrogen atoms strung together.”
