摘要
通过对空间PML的构造及PML中分裂场的特性分析,对FDTD计算中PML的应用进行了简化;同时对编程思想进行了改进。整个分析过程简明了然,无需对PML进行分区,也无需对顶角和棱边另外处理,极大地简化了计算过程。
The simplification of PML application and programming realization are presented based on the PML structure and computing characteristics of the split fields in FDTD calculations. In the new idea of PML application, the PML doesnt need to be split into subsections to respectively compute the fields, nor the comers and the special edges, which spares computer memory and time effectively and practicably. At last, the verification of the idea is given through numerical examples.
