强电磁脉冲条件下吸波材料面临的问题研究

Research on the problems faced with absorbing materials in the environment of high electromagnetic pulse

强电磁脉冲环境是未来战场隐身装备必须面对的主要威胁之一。本文分析了强电磁脉冲条件下吸波材料的失效机制,认为强电磁脉冲的非线性效应和热效应是导致其失效的最主要原因。进一步分析了提高吸波材料对电磁脉冲吸收能力和性能稳定性的途径,指出碳化硅类吸波材料是当前的最优选择,电磁超材料则是新的可行途径。

The high electromagnetic pulse(HPM) environment is one of the main threats for stealthy equipments。In this paper,the failure mechanisms of absorbing materials in HPM environment are analyzed,and it's considered that the nonlinear effect and thermal effect of HPM are the most important roles. Furthermore,the methods to improve the absorption capacity and performance stability of absorbing materials are analyzed. SiC material is the best choice for HPM protection at present and electromagnetic matematerial is a feasible approach in future.
