Engineers and scientists at Duke University have developed an “acoustic cloaking deivce” using “metamaterials”. The device passively disrupts sound waves in such a way that the device itself, and anything within it, can not be detected acousticly. The result is that the sound waves behave as if they are reflected from a flat surface. Professor of Electrical and Computer Engineering, Steven Cummer, is the leader of this design project.
