The lining of multilayer axial conductive yarn can change the properties of knitted fabric effectively and the shielding efficiency is better. The electromagnetic wave incidence angle increase would cause the polarization effect of surface current density on the knitted fabric.
The result shows that the shielding effectiveness increases nonlinearly with the increase of the conductivity of the fabric. The finite integral method was adopted to compute the shielding effectiveness in 0-18 GHz range, including different conductivities, fabric structure, layer and direction of axial yarn and different incidence angles of electromagnetic wave. Abstract In order to study the propagation law of electromagnetic wave in knitted fabric,the microstructure of weft-knitted fabric was modeled by SolidWorks software, and the simulation model was established by CST microwave studio.
