<p>The invention relates to a shielding panel for the attenuation of high frequency electromagnetic fields and disturbances. According to the invention, the panel is in the form of a layered structure composed of a nanoconductive layer with distributed impedance consisting of a sheet extruded from 80% recycled polyethylene, with additives, and 20% polyacrylonitril with the equivalent of 0.75% n-methylpyrrole of the total weight of the composite, an expanded polystyrene layer which forms a dielectric core, is dimensioned depending on the wavelength of the magnetic field to be shielded and in which there are cut some punched recesses in order to obtain a chiral honeycomb form, a nanoconductive layer with distributed impedance made on the basis of composites consisting of about 85% PE/PP extruded sheet additivated with oleic acid and about 20% polysulphone with the equivalent of 3.5% magnetite powder of the total weight of the composite, the structure being provided on the inside with 2 layers of aluminium sheets for protection.</p> |
