Study of Secondary Field Waves at Scattering of Nonlinearly Interacting Acoustic Waves by an Elongated Spheroid

The study and three-dimensional simulation of the field of the second harmonic wave at the scattering of nonlinearly interacting acoustic waves by an elongated spheroid are carried out in this work. The problem is presented in the elongated spheroidal coordinate system, and the foci of the spheroid coincide with foci of the spheroidal coordinate system. The description of the occurring wave processes is presented on the basis of the obtained relation for acoustic pressure of the second harmonic wave. The scattering diagrams for the acoustic pressure field of the second harmonic wave are presented, and three-dimensional models of a scattering diagram are created.
