Abstract:
In this talk, we will present some efficient high-order methods for acoustic wave scattering problems with bounded obstacles. The methods integrate a Dirichlet-to-Neumann technique for domain truncation, a perturbation approach for rough scatter and effective spectral solvers, which result in fast and stable methods robust for medium and high wave numbers.
