Abstract

The paper proposes the analytic modelling of flexible textile shields made of fabrics with inserted conductive yarns and metallic plasma coating in order to calculate their electromagnetic shielding effectiveness (EMSE). This manufacturing process is highly innovative, since copper plasma coating improves EMSE on the fabrics with inserted conductive yarns of stainless steel and silver with 10–15 dB in the frequency range of 0.1–1000 MHz, as shown by the measured EMSE values determined according to the standard ASTM ES-07 via the Transverse Electromagnetic (TEM) cell. On the other hand, modelling of EMSE for such conductive flexible shields gives an insight on estimating EMSE in the design phase of manufacturing the shield, based on its geometric and electrical parameters. An analytic model was proposed based on the sum of EMSE of the fabric with inserted conductive yarns and EMSE of the copper coating. The measurement results show close values to the proposed analytic model, especially in case of fabric with conductive yarns having stainless steel content.

磁控管等离子体涂层导电纱插入编织结构的建模及屏蔽性能测试

本文提出了插入导电纱和金属等离子体涂层织物制成的柔性纺织品屏蔽层的解析建模方法，以计算其电磁屏蔽效能。这种制造工艺是高度创新的，因为铜等离子涂层可以在0.1-1000 MHz的频率范围内，将不锈钢和银的导电纱线插入织物上，提高10-15 dB的EMSE，如根据标准ASTM ES-07通过横向电磁(TEM)电池测量的EMSE值所示。另一方面，对这种导电柔性屏蔽的EMSE建模，可以根据其几何和电气参数，在制造屏蔽的设计阶段估计EMSE。提出了插入导电纱织物的EMSE与铜涂层的EMSE之和的解析模型。测量结果与所提出的分析模型接近，特别是在含不锈钢导电纱线的织物中。
