摘要：

依据电磁屏蔽基本理论，总结了无孔金属板、有孔金属板和金属丝网格屏蔽体的屏蔽效能理论计算方法及公式。针对不同的织物类型或理论计算模型和方法，从有孔金属板、金属丝网格、拓扑结构模型及其他数值计算方面，综述了近年来关于电磁屏蔽织物屏蔽效能理论计算的研究进展。分析了现有电磁屏蔽织物屏蔽效能定量研究中存在的问题，指出应进一步研究纱线电磁参数及织物结构与屏蔽效能的理论关系。此外，指出在考虑纱线电磁参数和结构参数的基础上，建立织物屏蔽效能的解析公式用于指导工程计算为后续的研究方向。

Abstract:

According to the basic theory of electromagnetic shielding, the theoretical calculation methods and formulas of shielding effectiveness for sheet metal, perforated metal and metal wire mesh were summarized. For different types of fabric or the theoretical calculation model and methods, from perforated metal, wire mesh, topology structure model and other numerical methods, the research progress of the theoretical calculation of shielding effectiveness of electromagnetic shielding fabric in recent years were reviewed. The problems existing in the quantitative research of shielding effectiveness for electromagnetic shielding fabric were analyzed. The view that the theoretical relations between shielding effectiveness and electromagnetic parameters of the yarns, fabric structure need further study was pointed out. In addition, on the basis of the electromagnetic parameters and structure parameters of the yarns, subsequent research direction is to establish analytic formula used to guide the engineering calculation of shielding effectiveness of fabric.

Key words: electromagnetic shielding fabric, fabric, shielding effectiveness, equivalent model, empirical equation, theoretical calculation
