报告题目： Acoustic Boundary Conditions Due to High-contrast Material Inclusions

报告摘要：

In this talk, I will investigates the asymptotic behaviors of time-harmonic acoustic waves generated by an incident wave illuminating inhomogeneous medium inclusions with high-contrast material parameters. We derive sharp asymptotic estimates and obtain several effective acoustic obstacle scattering models when the material parameters take extreme values. The results clarify the connection between inhomogeneous medium scattering and obstacle scattering for acoustic waves, providing a clear criterion for identifying the boundary conditions of acoustic obstacles in practice. These new derived models also offer a fresh perspective on considering inhomogeneous medium inclusions with high-contrast material parameters.
