Cloaking of real world 3D objects now possible

(Nanowerk News. Jan 26. 2012) Researchers in the US have, for the first time, cloaked a three-dimensional object standing in free space, bringing the much-talked-about invisibility cloak one step closer to reality. This study shows how ordinary objects can be cloaked in their natural environment in all directions and from all of an observer's positions.
Published Jan. 26 in the Institute of Physics and German Physical Society's New Journal of Physics ("Experimental verification of three-dimensional plasmonic cloaking in free-space"), the researchers used a method known as "plasmonic cloaking" to hide an 18-centimetre cylindrical tube from microwaves.
