Caltech Researchers Create "Sound Bullets"

April 22, 2010

Alessandro Spadoni, Postdoctoral Scholar, and Chiara Daraio, Assistant Professor of Aeronautics and Applied Physics, have built a nonlinear acoustic lens that produces highly focused, high-amplitude acoustic signals dubbed "sound bullets." The combination of the acoustic lens and sound bullets have "the potential to revolutionize applications from medical imaging and therapy to the nondestructive evaluation of materials and engineering systems," says Professor Daraio.
