摘要

Woven fabric samples have been developed using composite yarn consisting of copper mono filament and PET filaments for evaluating electromagnetic shielding effectiveness (EMSE) against radiating electromagnetic wave spectrum over a frequency range 2.25 - 2.65 GHz. Coaxial transverse electromagnetic wave mode transmission method equipment has been used for testing in far field condition. It is observed that the weave and thread spacing of fabric samples significantly influence the shielding effectiveness as interpreted from the two way between subject ANOVA design. It is justified that aperture size and contact resistance of composite yarns in fabrics are the critical parameters in determining the shielding effectiveness of textile fabrics. The mechanism of fabric shielding is also discussed in detail using already established shielding theories which would help design fabrics for electromagnetic shielding.
