A protective fabric multiple thicknesses for the attenuation and the elimination of the irradiation the genesis, in particular for the (very) high frequencies (1mhz to 100 ghz.)

摘要

The invention relates to a device for increasing the attenuating power of metallized fabrics or fabrics with metallized yarns in relation to: electromagnetic fields, especially for frequencies from 1 MHz to 100 GHz, and more particularly for frequencies above 1 GHz; and electric fields. The invention relates to a device that can be used to reduce the size of the metallized fabric mesh and to increase the attenuating power of the metalized fabric and the frequency spectrum that can be attenuated, while retaining the suppleness, flexibility and breathability of the initial fabric. The device is formed by two or more fabric layers stacked on top of one another, said layers being optionally arranged in parallel and optionally in contact with one another. The device of the invention is particularly suitable for protecting living organisms, enclosures, dwellings and scientific instruments that have to be shielded from electromagnetic fields, especially waves, microwaves and high frequencies, and electric fields.
