Seismic wave simulation are often performed within limited region spanning from tens of meters, for civil engineerings applications, to hundreads of kilometers, for seismic hazard mitigation. In order to properly model the wavefield, accurate boundary conditions on the domains limits are needed. However, designing the boundary condition in a geological settings is very difficult as they rely on geological information outside from the domain of interest that are typically unknown. As such, a classical idea is to prevent any reflection of the wave at the boundaries. There is a variety of such boundary condition in the literrature. The object of this seminar will be to present one of these method: the Perfectly Matching Layer (PML).
