French Tribune reports a British physicist has won the top honor at the UK's Institute of Physics awards for conceiving the idea of an invisibility cloak. He pioneered the development of a new class of metamaterials, applicable to the invention of an invisibility cloak.
He published the idea in 2006 for the first time. IoP commended Sir Pendry's contribution towards low energy diffraction and the theory of surfaces. However, according to IoP, the idea of cloak of invisibility had the greatest impact scientifically and on the public imagination.
The metamaterials developed by Sir Pendry can be designed specifically to change the direction of electromagnetic waves. It happens by altering the nano-scale structure of the metamaterial rather than its chemistry, says French Tribune.
When, an object is covered in such a material, light waves flow around the object. Professor Pendry told BBC News that the idea was inspired by a very mundane material that was used to absorb radar. French Tribune notes Sir Pendry said in 2006, "What you're trying to do is guide light around an object, but the art is to bend it such that it leaves the object in precisely the same way that it initially hits it". This brings people under an illusion that nothing is there.
