Scientists Stitch up Cloaking Device
A transatlantic team of researchers has taken a big step towards their cloak of invisibility by successfully hiding a cylinder from microwaves, according to the journal Science and tabloid, The Sun.

Professor Sir John Pendry, winner of the Institute of Physics’s Dirac medal in 1996, and chair in Theoretical Solid State Physics at Imperial College, London, led a team of researchers at Duke’s University in North Carolina to develop a prototype device that can make objects undetectable by radar.

Professor David R Smith, Augustine Scholar and professor of electrical and computer engineering at Duke University, explained that the key lies in the metamaterials the cloak would be made of.

Metamaterials can be designed with very specific properties that allow scientists to control the path of electromagnetic radiation very precisely.
