An Upwind Leapfrog Scheme for Computational Electromagnetics: CL-FDTD

摘要：

This paper extends upwind-leapfrog scheme,initially developed from computational aeroacoustics and elastodynamics,into computational electromagnetics, and develops a novel Characteristic Line FDTD (CL-FDTD) method. In illustrating 2-D problems, this paper gives the implementation of the CL-FDTD method, and points out its merits over the FDTD method chosen for comparison. The results demonstrate that the CLFDTD method is less numerical dispersion,no requirement to deal with outer boundary conditions and it can precisely simulate accident signals that are difficult to treat with the conventional FDTD method.
