  • Publication number: 20100300744
    Abstract: A shielding article includes a first conductive layer and a second conductive layer spaced apart from the first conductive layer by a non-conductive polymeric layer defining a separation distance. The first conductive layer and the second conductive layer cooperatively provide a first shielding effectiveness. The first conductive layer, the second conductive layer, and the separation distance cooperatively provide a second shielding effectiveness that is greater than the first shielding effectiveness.
