UK scientists have invented a material that may allow the invention of an invisibility Cloak, just like the one used by Harry Potter. The material contains tiny structures that combined together to form a “metamaterial” which can manipulate light to render objects invisible.
Metamaterials work by channeling the flow of light at a fundamental level, controlling light waves in a precise fashion to achieve a particular effect. Similar materials have been developed before, however, they only worked for light in a part of the spectrum which the human eye cannot see.
