摘要

电磁能量选择表面(ESS)是参考频率选择表面(FSS)提出的一个概念。其基本思想是“电磁波的能量小于安全阈值时可以顺利通过，大于安全阈值时被自动屏蔽”。自适应开关特性能在不影响设备正常工作的前提下，有效保护强电磁脉冲。目前，ESS的设计很少采用窄带，屏蔽性能大于30dB。本文设计了一种工作在l波段的窄带ESS。CST结果表明，该结构的工作频段在1.426GHz ~ 1.623GHz之间，覆盖了机载GPS天线1.5~1.57GHz的工作频率范围。处于波透明状态时的插入损耗小于3dB，处于屏蔽状态时的屏蔽效率大于30dB。可用于机载GPS天线的大功率微波防护。

An L-band narrowband energy selective surface design

The Electromagnetic Energy Selective Surface (ESS) is a concept proposed by the Reference Frequency Selective Surface (FSS). The basic idea is that "the energy of the electromagnetic wave can pass smoothly when it is less than the safety threshold, and it is automatically shielded when it is greater than the safety threshold". The adaptive switching characteristic can effectively protect the strong electromagnetic pulse without affecting the normal operation of the equipment. At present, the design of ESS rarely has a narrow band and the shielding performance is greater than 30dB. In this paper, a narrow-band ESS operating in L-band is designed. The results of CST show that the working frequency band of the structure is between 1.426GHz and 1.623GHz, which covers the working frequency range of the airborne GPS antenna 1.5~1.57GHz. The insertion loss is less than 3dB when it is in the wave-transparent state, and the shielding efficiency is more than 30dB when it is in the shielding state. It can be used for high-power microwave protection of the airborne GPS antenna.
