Acoustic pulse propagation and localization in bubbly water.
Acoustic pulse propagation in bubbly water is studied using a self-consistent method. The acoustic transmission and backscattering are evaluated numerically. Under proper conditions, the localization of acoustic waves is identified within a range of frequency. The results show that when a short pulse is transmitted the waves of frequencies within the localization regime will be trapped in the system and reveal a coherent behavior. A phase diagram approach is used to describe the localization behavior.
