Abstract
Abstract A panel used in an enclosure for housing at least one electronic component, and an enclosure made of at least one of such panels is disclosed. The panel includes an electrically conductive layer, a separate, magnetically permeable layer connected to the electrically conductive layer, and a separate, extensionally damped layer covering at least 80 percent of a surface of the panel and attached to one or more of the electrically conductive layer and the magnetically permeable layer, where electrical and magnetic conductivity are maintained between all panels of the enclosure, and a ground is provided between circuitry of the electrical component and the electrically conductive layer.
