European scientists have claimed to have developed the first ever prototype of a 3-D “invisibility cloak”, similar to those worn by fictional wizard Harry Potter.

Researchers from the German Karlsruhe Institute of Technology and Imperial College London used the cloak, made using photonic crystals with a structure resembling piles of wood, to conceal a small bump — 0.00004 inches high by 0.00005 inches across — on a gold surface.

The researchers rendered the bump almost entirely invisible by “cloaking"” it in the new material, the Telegraph reported.

The “cloak” is composed of special lenses that bend light waves to suppress light as it is scattered from the tiny bump, says the study published in the journal Science.
