报告摘要 | This talk is concerned with the two-dimensional inverse elastic wave scattering by an unbounded rough surface with a Dirichlet boundary condition. We propose a novel sampling- type method to locate the rough surface by taking near-field measurements in the sense that the surface could be reconstructed more fully as long as the auxiliary parameter R > 0 is chosen to be sufficiently large. Numerical experiments are carried out to illustrate the effectiveness of the method. This is a joint work with Dr. Tielei Zhu. | ||
