Abstract: A 3D model of electromagnetic shielding fabric was constructed for the prediction of shielding effectiveness and optimization. The process of the fabric and electromagnetic wave interaction is simulated by using CST microwave studio. We computed the shielding effectiveness in 1—18 GHz range, including different incidence angle of electromagnetic wave and azimuth of electromagnetic wave. The result showed that the effect of dielectric constant of x axis and y axis on the shielding effectiveness of fabric was more significant. When the dielectric constant was small, the shielding effectiveness increased with the increase of the incident angle of electromagnetic wave. When the azimuth of electromagnetic wave changed, the incident angle of different electromagnetic waves had different effects on shielding effectiveness. This study had universal applicability, and provided a theoretical proof in optimizing design for high-performance shielding fabric.
