摘要
研究并实现了介质电与磁本构参数均为各向异性时的三维ANI-FDTD(anisotropic medium finite-dif-ference time-domain)方法及其并行计算。分析表明,电磁场分量节点的FDTD迭代计算均涉及到其邻近28个其他场分量节点值。在此基础上,分析了实行区域分割后ANI-FDTD并行计算中的数据通信规律。通过采用相邻子域重叠半个网格的区域划分方式,传递分界面两边相关节点的场值,实现了计算机局域网内各节点机的协同并行计算。数值计算结果表明了该方法和程序的正确性。
A three-dimensional anisotropic medium FI）TD （ANI-FDTD） of dyadic constitutive parameters ε ,μ ,σ and σin is discussed. A 28 field component grid model is given showing the relation of computation grid of a field component in ANI-FDTD with its neighboring grids. Based on this model, the way of message passing for field components between sub-domains in ANI-FDTD parallel computing are analyzed in details, and an FDTD parallel computing algorithm for anisotropic medium is proposed. Some numerical results are given to exemplify the feasibility of presented algorithm.
