| Abstract: | 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. |
