An Unconditionally-Stable FDTD Method Based on Split-Step Scheme for Solving Three-Dimensional Maxwell Equations

摘要：

A new split-step finite-difference time-domain (FDTD) method for solving three-dimensional Maxwells equations is presented,which is proven to he unconditionallystable and has simpler procedure formulation than the operator splitting (OS) FDTD method based on exponential evolution operator scheme. The proposed method has the new splitting forms along the x,y and z coordinate directions to reduce computational complexity and the second-order accuracyInboth time and space.Inthe application of a cavity,the proposed method produces 35％ reduction of the run time than the splitstep (SS)-FDTD (2,2) method.
