Development of an EM Simulation Software Based on the FDTD Method

摘要: 研制了一套用于场分析的电磁仿真软件。该软件基于时域有限差分法,能处理曲面边界目标,用户通过Visual Basic编写的界面输入物体结构参数、设置源及边界条件,并采用Fortran编写的计算模块调用VB生成的数据文件来进行仿真运算。通过同轴天线和谐振腔的模拟仿真对软件进行了验证测试,效果良好。

Abstract: An electromagnetic simulation software is developed. The software is based on the finite-difference time-domain (FDTD) method and can handle objects with curved surfaces and edges.The program includes a Visual Basic(VB) graphical user interface for graphically inputting object geometries and setting source and boundary conditions, and uses Fortran language to compute with a data file from VB. Examples that show the applications of the software for antennas and resonators are presented, and the results show good agreement with those reported in the published papers.
