GPU Accelerated DGTD Method for EM Scattering Problem from Electrically Large Objects

In this paper, we propose a discontinuous Galerkin time-domain (DGTD) method accelerated with Graphics Processing Unit (GPU) for scattering problem from electrically large objects. A ship model is simulated with the proposed DGTD method. The model is meshed with tetrahedron mesh and the numerical results of near field and far field of the ship model are illustrated in the paper.
