A simple and accurate discontinuous Galerkin scheme for modeling scalar-wave propagation in media with curved interfaces

Conventional high-order discontinuous Galerkin (DG) schemes suffer from interface errors caused by the misalignment between straight-sided elements and curved material interfaces. We have developed a novel DG scheme to reduce those errors. Our new scheme uses the correct normal vectors to the curved...
