【摘要】:通過比較不同細縫算法(TSF)計算誤差隨細縫寬度相對網(wǎng)格步長占比和頻率的變化,以及各TSF算法計算獲得的孔縫處及遠離孔縫位置場分布的差異,給出了時域有限差分(FDTD)計算中不同TSF算法的適用性。在此基礎上,將TSF算法用于分析工程中搭接縫結構的屏蔽效能問題,結果表明:將工程搭接縫等效模型與TSF算法結合,能夠使用FDTD快速地計算其屏蔽效能,有效解決了基于FDTD的含細縫復雜結構的屏蔽效能評估問題。
[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.
