摘要
利用电磁波传输理论推导出了电磁屏蔽材料阻抗公式,基于吸波材料的吸波原理,利用网格法及电磁参数广义匹配规律对影响表面反射率和总后向反射率的电磁参数进行分析与优化,研究结果表明,在电磁屏蔽材料的设计中表面反射率主要取决于分界面的阻抗匹配,介质内部影响电损耗主要因素为损耗因数εr'与μr',通过基于网格法对吸波材料的研究对提高材料的电磁屏蔽性能具有重要意义。
Using the theory of electromagnetic wave transmission, the impedance formula of electromagnetic shielding materials is deduced. Based on absorbing principle of absorbing material, the electromagnetic parameter that affects the surface reflectivity and the reflectivity is analyzed and optimized, which uses the grid method and electromagnetic parameters of the generalized matching rules. The research results show that the surface reflectivity in the design of electromagnetic shielding material mainly depends on the boundary surface impedance matching,and the main factors influencing power loss in the medium inside are the loss factors and εr' and μr'. The research of absorbing material based on grid method is of great significance to improve the electromagnetic shielding performance of materials.
