Electromagnetic shielding effectiveness of copper core-woven fabrics

Copper is selected as a conductive filler to produce copper core yarns to make woven fabric using a network analyser equipment, and the electromagnetic shielding effectiveness of these fabrics is measured in the frequency range of 20-18,000 MHz. With an increase in the number of conductive fabric layers, finer yarn count, warp density, weft density and cover factors, an increase in shielding effectiveness is observed. With an increase in copper wire diameter, a decrease in shielding effectiveness is observed.
