Abstract

Invisibility Cloaking is a scientific theory where objects can be hidden from sight. The first thing that comes to my mind when I hear the word invisibility is probably the fictitious Harry Potter, but surprisingly, Invisibility Cloaking was scientifically proven by Ulf Leonhardt and John Pendry in 2006. To make an object invisible, a cloaking device is placed around it. A cloaking device is made of artificially structured metamaterials, which are composed of metals and plastic. The cloaking device bends the light rays ensuring that they come in and leave the cloak in the same direction. In this paper, when I refer to an object becoming invisible, it means that the object cannot be seen, but it still exists in space, therefore, making the object hidden. This paper consists of the following topics of Invisibility Cloaking: (1) background theory, (2) optical media, (3) cloaking devices, (4) light trajectories, (5) conclusion, and (6) outlook.
