报告摘要:In this talk, we show our recent works on numerical methods for solving the forward and inverse problems of the wave equation in three dimensions by time-domain boundary integral equation methods. First, we consider the time-domain acoustic scattering by a sound-soft or an impedance obstacle in three dimensions. We reformulate it as a time-domain boundary integral equation. Then we propose a full discretization scheme by combining the convolution splines with a Galerkin method. Second, we study the time-domain acoustic scattering problem by multiple obstacles. An efficient numerical algorithm is proposed for simulating the multiple scattering effects via a decomposition method. Finally, we consider an inverse source problem for the wave equation. We derive two novel approaches for reconstructing the space-time dependent source function from the measurement of the wave field at a fixed point, by injecting high contrast droplets into the domain to image.
