Abstract
The influence of fabric weave type on the shielding effectiveness (SE) of electromagnetic shielding fabric (ESF) is studied in this paper. Some representative samples with different weaves are manufactured to test the SE using the waveguide testing system. The SE of each sample is obtained at different frequencies of the emission resource. Experimental results show that the yarn float which causes the aperture change of metal fiber arrangement is the key influencing factor without changing other parameters of fabric. Then, a new theory that the SE of the ESF with different weave types is determined by the number of the yarn floats in a weave repeat that is proposed. An evaluation model of the SE for the ESF with any weave type is established. By further verification, the results show that the method is satisfied and can be a basis for the evaluation of SE of the ESF with different weave types when other structural parameters of the fabric are not changed. The variation revealed in this paper can provide a theoretical guidance for the design, production, and evaluation of the ESF.
