3D Invisibility Cloak

Researchers create 3D invisibility cloak

European researchers have taken the world a step closer to fictional wizard Harry Potter's invisibility cloak after they made an object disappear, a study published Thursday in the journal Science showed.

Scientists from Karlsruhe Institute of Technology in Germany and Imperial College London used their cloak, made using photonic crystals with a structure resembling piles of wood, to conceal a small bump on a gold surface, they wrote in Science.

"It's kind of like hiding a small object underneath a carpet - except this time the carpet also disappears," they said.
