Scientists create new ‘invisible cloak’
Scientists claimed to have found an invisible cloak which hides you in broad daylight...but only works if you see in microwaves.
It is made up of a new metal called metascreen which consists of lengths of copper tape attached to a flexible polycarbonate film. It works by scattering and cancelling out incoming microwaves."When the scattered fields from the cloak and the object interfere, they cancel each other out and the overall effect is transparency and invisibility at all angles of observation," said Andrea Alu, a physicist.
