中文摘要：

依照电磁屏蔽理论,介绍了金属织物电磁屏蔽的机理。在此基础上,利用多物理场耦合分析软件COMSOL Multiphysics,建立三维仿真模型,分析了不同电磁波极化方向、不同半径和不同嵌织间距的奥氏体304不锈钢长丝,在不同辐射频率下对织物屏蔽效能的影响。仿真结果表明,极化方向、半径大小、嵌织间距和频率,对屏蔽织物都有显著的影响,这对不锈钢长丝防电磁辐射织物的开发和设计提供理论依据。

英文摘要：

According to the theory of electromagnetic shielding,principle of shielding effectiveness for textile containing metal fibers was briefly introduced.Based on this theory,a three-dimensional simulation model was established using the multi-physics coupled software COMSOL.Simulation test of several 304 austenitic stainless steel filament were done on different radius of stainless steel filament,different stainless filament distance,different polarization direction of EM wave and different radiation frequency.The result shows that fabric shielding effectiveness are effected significantly by different polarization direction,different radius and difference distance.These findings provide a theoretical proof in optimizing the designing of anti-electromagnetic radiation fabric made of metallic fiber fabric.
