    摘要:

    介绍了一种基于Y形能量选择表面的新型电磁脉冲防护材料,具有能量域上“低通高阻”的特性。对能量选择表面的理论基础和工作机制进行研究,论证了其透波率和外界场强的关系。通过建模仿真对能量选择表面的防护性能进行验证,并分析其结构尺寸对防护性能的影响。设计并仿真了双层Y形结构,与单层结构相比,双层结构对高功率电磁脉冲具有更好的屏蔽能力,并且保持了对于低功率信号良好的透波率。

    Abstract:

    In this paper,a new electromagnetic pulse (EMP) shielding material based on Ytype energy selective surface (ESS) was proposed. It had the feature of “low pass and high resistance” in the energy domain.The theory and the working mechanism of ESS was investigated.The relationship between the transmission efficiency and the electric field intensity was studied.The protection performance of ESS was verified through the modeling and simulation,and the influence of structure size on the protection performance was analyzed.A kind of doublelayer Ytype ESS was designed and simulated.Compared with the singlelayer structure, the doublelayer ESS had better EMP protection performance and maintained nice transmission efficiency of low power signals.
