World First: 3D Acoustic Cloaking Device
Steven Cummer , a professor of electrical and computing machine engineering at Duke University and his science lab has just revealed a three - dimensional Pyramids of Egypt - shaped gimmick that can cloak an object from acoustical detection . The cloak has been described in a new paper published inNature Materials . When wakeless waves hit an object , they jounce off and return to the distributor point of origin ....
