【摘要】：通过比较不同细缝算法(TSF)计算误差随细缝宽度相对网格步长占比和频率的变化,以及各TSF算法计算获得的孔缝处及远离孔缝位置场分布的差异,给出了时域有限差分(FDTD)计算中不同TSF算法的适用性。在此基础上,将TSF算法用于分析工程中搭接缝结构的屏蔽效能问题,结果表明:将工程搭接缝等效模型与TSF算法结合,能够使用FDTD快速地计算其屏蔽效能,有效解决了基于FDTD的含细缝复杂结构的屏蔽效能评估问题。
[Abstract]:By comparing the variation of (TSF) calculation error with the gap width relative to the grid step size and frequency, and the difference of the distribution of the slot location and the location field far away from the slot calculated by each TSF algorithm. The applicability of different TSF algorithms in finite-difference time-domain (FDTD) computation is given. On this basis, the TSF algorithm is used to analyze the shielding effectiveness of the lap joint structure in engineering. The results show that the equivalent model of the engineering lap joint and the TSF algorithm can be used to calculate the shielding efficiency quickly using FDTD. It effectively solves the shielding effectiveness evaluation problem of complex structure with fine seam based on FDTD.
