An Explicit Extrapolation Time-Stepping Scheme for Nodal DGTD Method

In this paper, an explicit extrapolation time-stepping scheme is introduced into discontinuous Galerkin in time domain method (DGTD). Compared to the other commonly used methods, the proposed time-stepping scheme can achieve high-order accuracy of time integration, and it works well with the lager time step. Numerical examples show the effectiveness and accuracy of the proposed algorithm.
