Abstract
A surface-compliant, removable and reusable EMI shielding cover for attenuating EMI emanation from openings in a shielding structure. An electrically conductive sheet or web is held over an opening in the shielding structure by an associated magnetic sheet, which is attracted to the metal shielding structure. The electrically conductive sheet or web, and the magnetic sheet are made of flexible material so that physical protrusions or non-planar surfaces on the shielding structure do not prevent the resulting EMI shielding cover from making complete contact around the periphery of an opening which is to be shielded. The conductive sheet and magnetic sheet can be made into a single composite EMI shield by applying an adhesive layer between the conductive sheet and the magnetic sheet.
