电磁屏蔽门屏蔽效能分析及仿真

Analysis and Simulation of the Shielding Effectiveness of the Electromagnetic Shielding Door

文中首先屏蔽效能和转移阻抗的定义,然后依据导电衬垫转移阻抗理论,建立了适用于不同类型电磁屏蔽门的屏蔽设计模型,,对衬垫类型、层数等因素进行了仿真分析,并通过测试数据验证了分析的正确性。

The paper first gives the definition of the shielding effectiveness and the transfer impedance . Then a generalized design model applying to different electromagnetic shielding doors is established according to the theory of aperture coupling and transfer impedance of the electric gasket Gasket types and the number of layers are analyzed and Simulated. Compared with the testing data , the correctness of the analysis is validated.
