Simply put, this cloak uses light waves that make it appear invisible or transparent. Scientists say, this concept involves complex calculations similar to Einstein's Theory of Relativity belongs. As reported by thechemicalblog, Wednesday (05/22/2013).
This magical cloak will create the illusion of a curved mirror looks flat and makes objects invisible hidden underneath. When light waves on the surface of the cloak, arch mirror is not deflect, but in such a way as to make it appear flat.
So far, the cloak of invisibility may work better in the range between 1500 to 2600 nm (nanometers). This may be outside the visible spectrum, but it has an important role in several applications, including telecommunications.
"Seeing something invisible with the eyes of an interesting experience," said the two scientists Joachim Fischer and Tolga Erin.
With the help of a laser method developed by CFN enables to produce a three-dimensional structure (3D) with the properties contained in natural or so-called metamaterials. Completion of these metamaterials will be able to produce the first invisibility cloak with camouflage rate at 700 nm light.
This means not only transparent, but also can produce the most expensive invisibility cloak that allows users to feel the warmth or heat when wearing a robe.
By using a thin copper plate (conductor) who has cleverly organized structure of silicon (a poor conductor), it can produce a material that can produce heat at different rates. (Amr)
