"Invisibility Cloaks" Could Break Sound Barriers

Contrary to earlier predictions, Duke University engineers have found that a three-dimensional sound cloak is possible, at least in theory. Such an acoustic veil would do for sound what the "invisibility cloak" previously demonstrated by the research team does for microwaves—allowing sound waves to [...]

First Demonstration of a Working Invisibility Cloak

A team led by scientists at Duke University's Pratt School of Engineering has demonstrated the first working "invisibility cloak." The cloak deflects microwave beams so they flow around a "hidden" object inside with little distortion, making it appear almost as if nothing were there at all.
