Abstract :
This paper considers the shielding effectiveness of nonwoven materials in the 1-8.5 GHz range using parametric semi-empirical models and experimental techniques. A range of materials based on metalised carbon fibres are considered with weights between 10 and 75 g/m2, thicknesses between 50 and 400μm, and measured shielding effectiveness between 35 and 100dB. A numerical model is presented and compared to experimental results.
