ABSTRACT:
A process and implementing construction includes an electrically independent EMI loading device comprised of an inner foam core surrounded by an electrically conductive envelope. The device is strategically positioned in resonant cavities located within a system enclosure housing electronic components and circuit boards and. In an example, the loading device is installed in a resonant cavity between a board-mounted component and an adjacent circuit board and is effective to decrease electromagnetic emission from resonating cavities.
