【摘要】 基于非均匀FDTD网格的电磁场模拟是一种解决诸多实际电磁场问题的通用、有效方法。本文介绍一个在直角坐标系下非均匀FDTD网格图形生成系统,具有友好的用户界面,可以快速、高效地产生1D、2D、3D FDTD网格,展现物体的几何图形,并且FDTD网格还可以动态地、可视化地得到检查、调节和修改。作为检验,本文以一实际结构为例,产生并显示了其网格图形。更多还原

【Abstract】 The electromagnetic simulation based on Non-uniform FDTD mesh is a genralized and efficient method to solve many practical electromagnetic problems. In this paper a Non-uniform FDTD Mesh Generation System in Cartesian Coordinate is introduced, which visually makes FDTD grids with an user friendly interface. The system can quicky and efficiently generate 1D, 2D, 3D, FDTD meshes and demonstrate object geometry patterns. Furthermore, FDTD meshes can also be checked, adjusted and modified dynamically and visually. As a validation, meshes of a practical structure are produced and illustrated.更多还原
