| 摘 要： | 为研究能量选择表面的防护性能,采用PIN二极管Spice模型,通过时域的场路协同仿真得到了能量选择表面(ESS)的瞬态响应波形。对影响插入损耗和防护效能的参数进行研究,优化结构参数,减小了尖峰泄漏。研究表明,双层ESS较单层ESS能够有效防护反向脉冲,同时增加单元金属条的长度能够减小脉冲尖峰泄露。通过强电磁脉冲辐照实验,验证了ESS小信号传输与强电磁脉冲防护的自适应防护能力,为强电磁脉冲的防护提供了可靠的方法。

| Abstract: | In order to study the protective performance of energy selective surface(ESS), this paper uses the PIN diode Spice model to obtain the transient response waveform of ESS by field-circuit co-simulation in time domain. The parameters that affect insertion loss and protective performance are studied, and structural parameters are optimized to reduce spikes. The results show that the double ESS can effectively protect the reverse pulse, and increasing the length of the metal strip can reduce the pulse spike. In this paper, the transmission of small signals and shielding of high power electromagnetic pulse are verified by high power electromagnetic pulse irradiation experiment, which provides a reliable method for HPM protection. |
