Till now, you must have heard or seen of an invisibility cloak in the Harry Potter series of books by J.K. Rowling, but none has thought of any such thing in reality. But, the researchers from the University of California, Berkeley, have changed the dream into reality and created an ultra-thin 'invisibility cloak'.

The principle behind the working of the cloak is that it is coated with thin layer of thousands of nanoscale dots that reflects back any light falling on its exterior, hiding the object under it. There is a film of 30 nanometers thick gold antennas coated on a 50-nanomater thick layer of magnesium fluoride. Most surprising fact about the cloak is that it not only hides the objects, but the user can not even able to see the cloak hiding the object.

Ziang Zhang, creator of the device, said that the cloak can be used in endless applications ranging from cosmetic to military and many more. The cloak can be used to hide beer belly at a beach or jagged edges and peaks in the object. It can also prove beneficial for military men and army people to hide them from the enemy.

It is interesting to know that the cloak is able to function on its own and requires no power source or camouflage, earlier technique used for invisibility purposes. The only drawback of the invisibility cloak is its size, as the larger samples will need to have greater resources and more technological input for making use of it.

The study published in the Journal Science has been titled as 'An ultrathin invisibility skin cloak for visible light".
