The analysis model of non-woven fabric made of synthetic fibers having different diameters for the non-magnetic noise suppressor is developed and the relationship between the wave impedance of free space is considered. The shielding effectiveness to the plane wave can be calculated using the sheet resistance by regarding the non-woven fabrics as a continuous metal sheet. Therefore, it is shown that the low wave-impedance in the fine fiber layers generates high shielding effectiveness.
