摘要

本文研究了核爆炸产生的短电磁脉冲通过通信电缆的穿透特性。建立了短电磁脉冲在长同轴电缆内感应瞬态电流和电压的计算模型。考虑了电缆位于上方(架空电缆)和半空间损耗介质内(埋地电缆)的两种情况。在频域和时域上计算了感应护套电流和内部电压。对架空同轴电缆和地埋同轴电缆进行了不同电缆参数和入射角的研究和讨论。

The penetration of nuclear electromagnetic pulses (EMP) through shielded communication cables

In this paper, we investigate the penetration characteristics of short electromagnetic pulses generated by nuclear explosions (EMP) through communication cables. A model is developed for determining the transient currents and voltages induced within a long coaxial cable by a short electromagnetic pulse. The two cases of cables located above (aerial cables) and within a half-space lossy dielectric (buried cables) are considered. The induced sheath currents and internal voltages are computed in both frequency and time domains. The effects of different cable parameters as well as the angle of wave incidence have been investigated and discussed for both aerial and buried coaxial cables.
