    • An improved radio frequency wave attenuating wall (ceiling or floor) or door material comprises a laminated structure having as an integral part thereof one or more layers of a viscoelastic material which also functions as a glue and one or more electrically conducting layers. An electrically conducting material such as tape or a formed metal channel provides an electrical connection between the electrically conducting material and an exposed outer surface of the laminated structure. In one embodiment the electrically conducting material is paint. In one embodiment, standard wallboard, typically gypsum, comprises the external surfaces of the laminated structure and one or more conductive layers are constructed between the gypsum exterior. In one embodiment, the conducting layer material is selected to provide physical security in addition to radio frequency wave attenuation. The construction is such that acoustical attenuation is also achieved.
    • 改进的射频波衰减壁(天花板或地板)或门材料包括具有其一部分的一层或多层粘弹性材料的层压结构,其也用作胶和一个或多个导电层。 导电材料如带或形成的金属通道在导电材料和层压结构的暴露的外表面之间提供电连接。 在一个实施例中,导电材料是涂料。 在一个实施例中,标准墙板(通常为石膏)包括层压结构的外表面,并且在石膏外部之间构造一个或多个导电层。 在一个实施例中,选择导电层材料以提供除了射频波衰减之外的物理安全性。 这样的结构使得也可以实现声学衰减。
