Investigation of the nonlinear propagation of ultrasound through a bubbly medium including multiple scattering and bubbl-bubble interaction: Theory and experiment

Understanding of the propagation of ultrasound through a bubbly medium is a challenging task because of the nonlinear dynamics of the bubbles and their effect on the attenuation and sound speed of the medium. The majority of the studies on this subject apply linear models, which will generate inaccurate results, especially at higher-pressure excitations. These studies have also ignored the effect of bubble-bubble interaction and nonlinear multiple scattering.
