Abstract
A system and method for mitigating EMI in an electronic device rely on a set of foam dummy plugs specially configured for insertion into socket connectors according to connector type. The foam plugs have no electrical terminals or wiring, but are made from a foam composite material that attenuates electromagnetic radiation by absorption. The foam composite material includes a foam matrix and electrically conductive particles impregnated within the foam matrix. A handle may be unitarily formed with the foam plug. The handle may include a stamped through-hole, forming a ring, to facilitate insertion and removal of the dummy plugs by hand.
