Abstract

Linear lightning diffusion into a Faraday cage is studied. An early-time integral valid for large ratios of enclosure size to enclosure thickness and small relative permeability ({mu}/{mu}{sub 0} {le} 10) is used for this study. Existing solutions for nearby lightning impulse responses of electrically thick-wall enclosures are refined and extended to calculate the nearby lightning magnetic field (H) and time-derivative magnetic field (HDOT) inside enclosures of varying thickness caused by a decaying exponential excitation. For a direct strike scenario, the early-time integral for a worst-case line source outside the enclosure caused by an impulse is simplified and numerically integrated to give the interior H and HDOT at the location closest to the source as well as a function of distance from the source. H and HDOT enclosure response functions for decaying exponentials are considered for an enclosure wall of any thickness. Simple formulas are derived to provide a description of enclosure interior H and HDOT as well. Direct strike voltage and current bounds for a single-turn optimally-coupled loop for all three waveforms are also given.

法拉第笼中的线性扩散
研究了闪电在法拉第笼中的线性扩散。本研究使用的早期积分适用于较大的封闭尺寸与封闭厚度之比和较小的相对渗透率({mu}/{mu}{sub 0} {le} 10)。本文对现有的电厚壁外壳附近雷击响应解进行了改进和扩展,计算了由衰减指数激励引起的变厚度外壳内附近雷击磁场(H)和时间导数磁场(HDOT)。对于直接打击场景,对外壳外由脉冲引起的最坏情况线源的早期积分进行了简化和数值积分,以给出最接近源位置的内部H和HDOT以及与源距离的函数。对于任意厚度的外壳壁,考虑了衰减指数的H和HDOT外壳响应函数。推导出简单的公式,给出了对围护结构内部H和HDOT的描述。给出了三种波形下单匝最优耦合环的直接冲击电压和电流边界。
