Researchers from the U.S. Naval Research Laboratory and the University of Texas at Austin have applied to acoustic waves the concept of "scattering cancellation," which has long been used to systematically cancel the dominant scattering modes of electromagnetic waves off objects. The work provides fundamental new tools to control acoustic scattering and should improve the ability to make acoustic measurements in the laboratory. It is described in this week's Journal of Applied Physics.
