Abstract In this paper, the electromagnetic shielding effectiveness results of the plain weave composite fabric and the analytical solution of metal mesh were investigated. The composite fabric made of cotton yarns twisted with 50 µm copper filaments was used in the experiment. As the fabric was weaved and stretched, it had square shaped apertures which had length of 1.2 mm. The electromagnetic shielding effectiveness of these fabrics was measured in the frequency range of 1.7–2.6 GHz via WR430 waveguide system. In order to model the shielding results of the aforementioned fabric, an analytical solution which facilitates to calculate shielding effectiveness of metal mesh, was taken into consideration. Due to the physical similarity between the fabric geometry and metal mesh structure, the values of fabric characteristics were substituted in analytical solution. A statistical approach showed that the measured SE results of plain weave composite fabric fitted in the analytical solution for metal mesh in 1.82–2.6 GHz frequency range with strength of 30–36 dB. Thus, depending on desired shielding efficiency the physical texture of shielding fabric can be determined analytically.

用于电磁屏蔽应用的平纹复合织物等效分析模型

摘要 本文研究了平纹复合织物的电磁屏蔽效能结果和金属网的解析解。实验中使用由棉纱加50μm铜丝制成的复合织物。当织物被编织和拉伸时，它具有长度为 1.2 毫米的方形孔。这些织物的电磁屏蔽效能是通过 WR430 波导系统在 1.7-2.6 GHz 的频率范围内测量的。为了模拟上述织物的屏蔽结果，考虑了便于计算金属网屏蔽效果的解析解。由于织物几何形状和金属网状结构之间的物理相似性，在解析解中替换织物特性的值。统计方法表明，在 1.82–2.6 GHz 频率范围内，强度为 30–36 dB 的金属网解析解中拟合的平纹复合织物的测量 SE 结果。因此，根据所需的屏蔽效率，可以分析确定屏蔽织物的物理质地。
