Step aside, Harry Potter… researchers have made an invisibility cloak of their own. The research team from Berkeley Lab created a “carpet cloak” from nanostructured silicon that conceals the presence of objects placed under it from optical detection.
This video shows how a beam of light is obstructed by an object in a flat surface and casts a shadow until the object is cloaked, at which point the light is reflected as if the surface were still perfectly flat.
