This 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.
