Abstract :
On the basis of a quasioptic approximation method the nonlinear interaction of Gaussian sound beams with different curvature radii of the wave front on the boundary is investigated. A numerically analysis of the amplitude characteristics of the secondary sound field of the difference frequency is also presented
