摘　　要：针对高功率电磁脉冲对电子元器件、组件、系统等的强电磁干扰问题,借助超材料强谐振损耗特性和接地层反射特性,设计了一种耐高功率微波(HPM)辐照的宽频吸波超材料。该超材料在X波段反射率达到-12 dB,具有93%以上的吸收效率,并且在电场为20 kV/m、脉宽为1 000 ns、重复频率为10 Hz的强电磁环境条件下单次辐照50 s后,材料温度基本未上升,吸波性能保持不变,无损伤发生,说明宽频吸波超材料在HPM辐照下性能稳定。宽频吸波超材料可有效保护载体平台上的其他电子设备,解决在高功率电磁脉冲辐照下的强电磁干扰问题,提高电子系统的强电磁防护能力。In view of the strong electromagnetic interference of high power electromagnetic pulse on electronic components,components and systems,a kind of broadband wave absorbing metamaterial resistant to high power microwave(HPM)irradiation is designed by virtue of the characteristics of strong resonant loss and ground reflection of metamaterial.The reflectivity of this material in the X-band reaches-12 dB,and it has an absorption efficiency of more than 93%.After a single irradiation of 50 s in a strong electromagnetic environment with an electric field of 20 kV/m,a pulse width of 1000 ns,and a repetition frequency of 10 Hz,the temperature of the material basically does not rise,and its absorption performance remains unchanged without damage.This indicates that the broadband absorbing metamaterial has stable performance under HPM irradiation.The broadband absorbing metamaterial can effectively protect other electronic equipment on the carrier platform,solve the problem of strong electromagnetic interference under high power electromagnetic pulse irradiation,and improve the strong electromagnetic protection ability of electronic system.
