Wu, Ru-Shan | Xie, Xiao-Bi
The long-term goal is to develop a new method and the code to simulate 3D acoustic/elastic wave propagation and interaction with the ocean water and ocean bottom environment. The method will be applied to numerical simulations and imaging to study the wave/sea-bottom interaction, energy partitioning, scattering mechanism and other problems that are crucial for many ocean bottom-surveying techniques. Our understanding on shallow water acoustic wave propagation and its interaction with sediments can be improved. Objectives are to improve and develop the ECS (Elastic Complex-Screen), a new one-way elastic wave propagation method, and apply it to the ocean bottom environment to study the elasto-acoustic wave propagation in complex laterally heterogeneous media, including rough interface and random volume heterogeneity.
