Physicists in Germany are refining the structure of an invisibility cloak to such an extent that it is also effective in the visible spectral range. The minute invisibility cloak is smaller than the diameter of a human hair. It makes the curvature of a metal mirror appear flat, as a result of which an object hidden underneath becomes invisible
