Abstract

In this paper the electromagnetic shielding effectiveness (EMSE) of knitted fabrics made of copper, silver and stainless steel blended conductive yarns were analyzed statistically. Data obtained by the experiments carried out in 1.7 - 2.6GHz frequency band with the help of waveguide system was evaluated by statistical methods. A total of 29 different knitted fabric samples were used in the experiments, including rib, weft, milano, lacoste and cardigan types. In order to test the stability of shielding effectiveness (SE) descriptive statistics were presented for all fabric samples. Subsequently, data was distributed into clusters by means of ANOVA method. In this way, the fabrics with the worst and best shielding performance were found at 95% confidence level. The statistical findings overlapped with experimental results.
