Invisibility Cloak, Sort of
Scientist create a partial invisibility cloak device that redirect particular wavelengths of light, making them go around object like water flowing and rocks in a stream.
"The microwaves come in and are swept around the cloak and reconstructed on the other side while avoiding the interior region," said study team member David Smith at Duke University's Pratt School of Engineering. "So it looks as if they just passed through free space."
