摘要 介绍了时域有限差分(FDTD)方法的基本原理,提出了基于环路法(CP)的三维细孔缝仿真算法(TSF)。用细化网格的FDTD和用亚网格的TSF两种算法,分别对相同的细孔缝模型进行了仿真计算。结果表明亚网格TSF算法与细化网格的FDTD算法无论是在时域还是在频域上的仿真计算结果都吻合得很好,而且应用亚网格TSF算法可以极大的缩短计算时间。最后利用TSF算法对屏蔽机箱进行数值仿真,得到了屏蔽机箱开孔3 m远处的电场频域曲线。 Introduce the basic principle of finite difference time domain method（FDTD） and put forward the Thin - Slot Algorithm（TSF） based on CP method for the analysis of the effect of a shielding box, using the same narrow apertures model to compare the results computed by FDTD and TSF. The results show that they are agree well with each other not only of frequency domain result but also of time domain result. When we use the TSF Algorithm the computation time can reduce greatly, Finally, we use the TSF Algorithm to numerical emulation the effect of a shielding box and obtain the cure of the apertures electric field frequency domain result at 3 m distance.
