We’ve reported on real-world invisibility cloaks before, but according to Discovery News such a thing actually exists now, albeit on a very small scale:
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.
invisible soldier“We put an object under a microscopic structure, a little like a reflective carpet,” said Nicholas Stenger, one of the researchers who worked on the project.
“When we looked at it through a lens and did spectroscopy, no matter what angle we looked at the object from, we saw nothing. The bump became invisible,” said Stenger…
