Invisibility Cloak from 'Metamaterials'

Theoretical Blueprint for Invisibility Cloak Reported: "'The cloak would act like you've opened up a hole in space,' said David R. Smith, Augustine Scholar and professor of electrical and computer engineering at Duke's Pratt School. 'All light or other electromagnetic waves are swept around the area, guided by the metamaterial to emerge on the other side as if they had passed through an empty volume of space.'

Electromagnetic waves would flow around an object hidden inside the metamaterial cloak just as water in a river flows virtually undisturbed around a smooth rock, Smith said."

Only one problem with this theory though. Just like no one will see you when you are within that space, you will not see anything. :)

Check this work from the Uni of Tokyo:

the same concept can be used to send electromagnetic waves to the interior of the cloak so that outside can be "seen"
