When something is invisible, it creates a magical effect and a questioning mind and this makes the viewers probe into the field of invisibility technology. Really is there something called invisibility cloaking? Fictional movies have used invisibility cloaking to make something disappear for some time and when the cloak is removed, the thing or the person appears again. In 2008, a physicist named Michio Kaku prophesied that a feasible invisibility device like the ones used in Star Trek can emerge from research laboratories. He also quoted David Smith of the Duke University who had used meta-material to bend light around an object and also he quoted that German scientists have found that a meta-material can make the red light go around the object. This has become true, and due to the advanced technologies and the developments in the scientific research, a real world cloaking device has been created which has the capacity to obscure things to no less than one wavelength of electro-magnetic emissions.
