【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]:A new type of electromagnetic pulse protection material based on Y-shaped energy selective surface is introduced, which has the characteristics of "low permeability and high resistance" in the energy domain. The theoretical basis and working mechanism of the energy selective surface are studied. The relationship between the transmittance and the external field strength is demonstrated. The protective performance of the energy-selective surface is verified by modeling and simulation, and the influence of the structure size on the protection performance is analyzed. The double-layer Y-shaped structure is designed and simulated, which is compared with the single-layer structure. The double layer structure has better shielding ability for high power electromagnetic pulse and good transmittance for low power signal.
