ABSTRACT:
Novel devices for providing shielding from and absorption of broadband electromagnetic radiation, and methods of manufacturing and using these devices, are disclosed. The device is comprised of a perforated electrical absorbing layer, containing conductive polymers, laminated to a metal plate. Additional layers may be incorporated into the device including one or more additional layers of electrical absorbing layers, magnetic absorbing layers and impedance matching layers.
