Cloaking' a 3-D object from all angles demonstrated

Researchers have "cloaked" a three-dimensional object, making it invisible from all angles, for the first time.

"Previous efforts that have made 3-D objects disappear have relied upon a "carpet cloak" idea, in which the object to be cloaked is overlaid with a "carpet" of metamaterial that bends light so as to make the object invisible.

Now, Andrea Alu and colleagues at the University of Texas at Austin have pulled off the trick in "free space", making an 18cm-long cylinder invisible to incoming microwave light."
