      Real compact-2D-FDTD method and its application in electromagnetic properties

      摘要:
      探讨了电大尺寸目标中电磁波传输特性分析方法问题,提出了实变量Compact-2D-FDTD方法与MPI-OpenMP并行FDTD方法,并推导了实变量Compact-2D-FDTD方法基本公式.实验表明,实变量Compact-2D-FDTD方法和MPI-OpenMP并行FDTD方法与传统FDTD方法计算结果相吻合,且计算时间明显减少,因此,有效地解决了电大尺寸目标仿真时的计算时间长和内存需求大的问题.
      Abstract:
      In this paper,the analysis method of electromagnetic wave transmission characteristics of electrically large objects is discussed,and the real variable Compact-2D-FDTD method and MPI-OpenMP parallel FDTD method are proposed,and basic formulas of real variable Compact-2D-FDTD method are derived.The results of experiments show that the real variable Compact-2D-FDTD method and MPI-OpenMP parallel FDTD method with the conventional FDTD method are very good agreement with calculated results and less computation time.Therefore,the problems of electrically large size objects simulation computation time length and the large memory requirement are solved.
