Abstract: The problem of mathematically modeling the nonlinear interaction of ultrasound beams is addressed. The counterpropagation model is studied and a new model, called the copropagation reflection model, is proposed. The new model shows that the copropagation of the probe and the reflected pump leads to nonlinear interaction. Simulation of the nonlinear interaction of the pump and the probe shows that the sensitivity of the copropagation reflection is higher than the counterpropagation nonlinear interaction. The theoretical curves representing the different models are compared with experimental data obtained under different experimental conditions, and the experimental study of the nonlinear interaction shows that the copropagation reflection model is confirmed by experimental data. This model offers the possibility of achieving greater accuracy in nonlinear imaging.
