    • A panel for an electromagnetic shield includes a light-weight, porous, electrically-conductive core layer of metallic foam having generally parallel opposed surfaces and a face sheet having rigidity properties superior to the rigidity properties of the core layer laminated to a surface of the core layer. Alternatively, a panel for a broadband electromagnetic shield includes a composite fiber-reinforced core having opposed surfaces and a layered electrically-conductive composite cover disposed on a surface of the core. The cover includes a first stratum of porous metal exhibiting pronounced low-frequency electromagnetic shielding properties and a second stratum of electrically-conductive elements exhibiting pronounced high-frequency electromagnetic shielding properties secured in an overlapping electrically-continuous relationship to the first stratum, the first stratum being a metallic lattice, and the electrically-conductive elements being a non-woven veil of electrically-nonconductive metal-coated fibers.
    • 用于电磁屏蔽的面板包括具有大致平行的相对表面的金属泡沫的重量轻,多孔,导电的核心层和具有优于层叠到芯的表面的芯层的刚性特性的刚性特性的面板 层。 或者,用于宽带电磁屏蔽的面板包括具有相对表面的复合纤维增强芯和设置在芯的表面上的层状导电复合材料盖。 该覆盖物包括具有显着的低频电磁屏蔽性能的多孔金属的第一层和具有以与第一层重叠的电连续关系固定的显着的高频电磁屏蔽性能的第二层导电元件,第一层 是金属晶格,并且导电元件是非导电金属涂覆的纤维的非织造面纱。
