A finite difference - discontinuous Galerkin method for the wave equation in second order form
Siyang Wang, Gunilla Kreiss
We develop a hybrid spatial discretization for the wave equation in second order form, based on high-order accurate finite difference methods and discontinuous Galerkin methods. Th…

On the stability analysis of perfectly matched layer for the elastic wave equation in layered media
Kenneth Duru, Balaje Kalyanaraman, Siyang Wang
In this paper, we present the stability analysis of the perfectly matched layer (PML) in two-space dimensional layered elastic media. Using normal mode analysis we prove that all i…
