A well-designed electromagnetic shield, whether it be a shielded room, an electronic equipment item’s chassis, or a small shield on a circuit board, can be rendered useless by the power and signal I/O conductors that need to penetrate the shielding boundary. This demonstration by John Kraemer shows the effects of conductors that penetrate a shield, and provides insight as to how the degradation can be limited.
