摘要
高空电磁脉冲(high altitude electromagnetic pulse, HEMP)幅值强、频谱宽、覆盖范围广,可对大面积范围内的绝大多数未加固的电子电力系统造成损伤。系统级HEMP耦合分析是HEMP评估和加固防御的基础。本文介绍了作者团队近10年来在系统级HEMP耦合分析方法方面的研究进展,主要包括两方面:一是针对局域多尺度多元复杂系统HEMP耦合分析的瞬态电磁拓扑方法;二是针对广域分布式系统HEMP耦合分析的,基于有效耦合长度的网络耦合分析方法。
High-altitude electromagnetic pulse(HEMP)with high magnitude,wide bandwidth,and large coverage,can damage most unhardened electronic and electrical systems and draw many attentions worldwide.The analysis of HEMP coupling into systems is the basis for the HEMP evaluation and protection.This paper introduces the research progress of system level HEMP coupling analysis methods,which has been made by the author’s team.The progress includes two aspects,one is the transient electromagnetic topology method which is applied to analyze HEMP coupling into local multi-scale multivariate complex systems,the other is the method based on effective coupling length,which is employed to analyze the HEMP coupling into wide area distributed systems.
