Dianci bileiqi, 2014 直击雷引起的建筑物内部电磁干扰问题一直是雷电防护方面的研究重点。采用基于矩量法（Mo M）开发的三维电磁场仿真软件FEKO,在CADFEKO模块中对某建筑物进行雷击电磁仿真,用场理论对模型进行扫频求解,并将得到的频域结果在POSTFEKO模块中进行傅里叶逆变换（IFFT）得到时域结果,然后对计算结果进行分析和讨论。结果表明,基于FEKO的电磁场仿真对建筑物内部雷电防护工程具有重要的参考价值。

IET Science, Measurement &Technology, Volume 19, Issue 1, January/December 2025.This study demonstrates that the conventional 8% physical volume rule for Equipment Under Tests (EUTs) in reverberation chambers is an unreliable guideline for maintaining field uniformity. Our full‐wave simulation results prove that an EUT's electrical size and geometric shape are the more critical factors.
