| 摘 要： | 为解决强电磁脉冲防护中屏蔽与正常信号收发之间的矛盾，研究了一种既能隔离强电磁脉冲，又能保证被保护设备信号正常收发的能量选择表面（ESS）。基于可变表面阻抗理论研究ESS的防护机理；根据强电磁效应改变二极管的阻抗特性和实现能量选择的特点，设计了一种正反并联的二极管对阵列组成的可防护线极化强电磁脉冲的ESS，并进行仿真和实验分析。结果表明：所设计的ESS对弱电磁信号的插入损耗小于2 dB，对强电磁信号的隔离度大于20 dB，实现了能量低通的选择特性。 |

| Abstract: | An Energy Selective Surface(ESS)was presented to manage the conflicting requirement for shielding protection from high-power electromagnetic pulses(EMPs)and normal transmission of signals,as it can isolate high-power EMPs but allow the device to send and receive signals normally.Using the vari able impedance surface theory,the protection mechanism of the ESS was investigated.As the energy selec tive characteristics offered by diode impedance could be controlled by high power microwave,we designed an ESS made of a diode array to provide protection from the effects of linear polarized EMPs.The perfor mance of the designed ESS had been simulated and tested.Results show that insertion loss of the proposed ESS to normal signals is less than 2 dB,and isolation to intense EMPs is more than 20 dB.Therefore the energy low-pass performance is achieved. |
| Keywords: | Energy Selective Surface(ESS) high power electromagnetic pulse protection protection mechanism diode array |
