摘　　要：随着空间电磁场强度越来越高,现代数字化设备安全受到严重威胁。“前门”作为对外信息交互通道,也是电磁能量耦合的重要途径。瞄准“前门”电磁防护需求,融合频率选择和能量选择理念,设计了一种小型化强电磁辐照防护结构。利用能选结构,将工作频带内大部分能量反射,利用频选结构,进一步降低带外透射能量。仿真结果表明,所设计电磁防护结构在工作通带内具有较低的插入损耗,对高功率微波、高空核爆电磁脉冲、干扰等带内强电磁能量与带外信号具有较高的屏蔽效能。As the electromagnetic field intensity in space increasing,the safety of modern digital equipment are seriously threatened.The front door,as an exchange channel for external information,is an important path for electromagnetic energy coupling.Aimming at the demand of electromagnetic protection of the front door,this paper designs a miniaturized protective cover structure for electromagnetic radiation by fusing the frequency selection and energy selection concepts.Most of the energy is reflected through energy selection structure and residual energy is further reduced through the frequency selection structure.The simulation results show that the designed structure for electromagnetic protection has low insertion loss in the working passband,and high shielding effectiveness for high power wave(HPM),high altitude nuclear explosion electron pulse,interference and other strong in-band electromagnetic energy and out-of-band signals.
