Engineers use shielding, grounding, and clever materials to block unwanted currents and keep devices running smoothly. Think Faraday cages, but for everyday gear — a conductive enclosure, a proper ground path, and careful seams so stray RF can’t sneak inside. Add damping materials for vibration, breathable vents fo
