摘要
A generalized high-order finite-difference method [discrete singular convolution-symplectic integrator propagator (DSC-SIP)] is proposed to analyze the electromagnetic scattering problem in which the time difference is discretized by the SIP and the spatial difference by the DSC. When compared with the standard finite-difference time-domain (FDTD) method, the DSC-SIP method not only has higher stability and accuracy but also can save the computing memory space and CPU time with suitable meshes. Numerical examples are provided to show the high stability and effectiveness of the proposed method. (C) 2011 Wiley Periodicals, Inc.
