Abstract :Recently, the advantages of protective textile materials such as cost effectiveness, flexibility, lightweight etc. over metal plates are emphasized in many studies. However, these studies did not provide a comparison of protective performances between fabrics and metal plates. In this study, electromagnetic shielding performances of copper plate and metal composite woven/knitted fabrics were compared. For this purpose, electromagnetic shielding effectiveness of single and double layer copper plate and metal composite fabrics were measured in vertical and horizontal directions. As a result, copper plate showed better performance than composite fabric samples in both measurement directions. However, the composite fabrics did not show an effective performance in horizontal direction. EMSE behavior of copper plate was similar for both direction due to the isotropic structure and this performance maintained in higher frequency level. On the other hand, gaps in the structure of composite fabrics caused the decreasing in EMSE performance against increasing frequency.
