The Daily Mail Online reported that an invisibility cloak will be a reality within five years, according to researchers from Purdue University in Indiana, U.S.A.
According to the article, the researchers are using principles of nanotechnology and metamaterials in conjunction with Einstein’s theory if general relativity to create the electromagnetic cloak. It will work by bending the light around itself to make the cloak and the object inside it hidden.

“The whole idea behind metamaterials is to create materials designed and engineered out of artificial atoms, meta-atoms, which are smaller than the wavelengths of light itself,” said Professor Vladminr Shalaev, according to the article.
