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.
