Abstract
AbstractThis article presents an explicit fourth‐order accurate Finite Difference Time Domain (FDTD) method, in which the fourth‐order accurate staggered Adams‐Bashforth time integrator is used for temporal discretization and the fourth‐order accurate Taylor Central Finite Difference scheme for spatial discretization. The analysis shows that the numerical dispersion of the new FDTD method is much lower than that of the Fang‐FDTD method and the stability restraint of the new FDTD methods is relaxed in comparison with that of the FDTD method using the Staggered Backward Differentiation time integrator. © 2007 Wiley Periodicals, Inc.
