Abstract

An approach based on separation of the stages of nonlinear distortion and diffraction is used to describe the field in the focal region of a converging beam of finite-amplitude sound. It is shown that nonlinear distortions increase the gains of focusing systems and narrow the peak-pressure and intensity distributions. At intensities above the shock-formation level the focusing-system gains decrease, and the points of maximum wave amplitude shift toward the radiator. Calculations are carried out for standard acoustic concentrators with nonlinear effects taken into account.
