Patent no. Patent application No. a 2010 01173/25.11.2010<br />
The invention refers to one selective shielding system which<br />
allows the selective shielding of the electromagnetic<br />
radiation in the 500 MHz-20GHz range, simultaneously and<br />
selectively for several frequency bands, with the central<br />
radiation frequency controlled through the lengths of the<br />
microwires by combining the magnetic pr<strong>op</strong>erties of the<br />
wires with their geometrical distribution. The selective<br />
shielding system consists in CoFeSiB or FeSiB amorphous<br />
Description<br />
magnetic glass-coated microwires with diameters ranging<br />
EN<br />
between 10 µm and 30 µm and different lengths, in the<br />
centimeter range, parallel aligned in successive rows or<br />
randomly disposed on a nylon foil impregnated with an<br />
adhesive superficial layer, or dispersed in a dielectric matrix.<br />
Applications:<br />
• electromagnetic shielding<br />
• smart composite materials industry<br />
• security applications.<br />
