Although the time denied by some scientists about the impossibility of making seemingly not cloak Harry Potter. However, the initiator of the idea to make sure that the robe would be realized in the near future.
Michal Lipson of New Yorks's Cornell University and Xiang Zhang of the University of California are the two scientists who managed to make cloth with materials similar functions Harry Potter robes.
Someone will be able to take refuge in these robes and not visible to the user lain.Namun can see other people and their activities as usual without any known to exist.
Cloak Lipson and Zhang design is made of glass material which is very thin with the effects of a very subtle impact. So that was launched Telegraph.
This material is then bend light around objects in three dimensions, and this effect seemed to cloak users "disappeared" and not visible to others.
The technique used this robe, that is by using light bending effects depend on the refraction of turning. This effect is similar to what we usually see on a straw that looks bent when placed in a clear glass of water.
By using nano-scale materials is measured in billions per meter size, scientists then set the bending of light around objects in three dimensions to create user robes "disappeared".
The material used in making these robes used in wavelength for telecommunications indutri interests that are part of the spectrum.
