Electromagnetic Control and Radio Frequency Interference Absorption
Conductive surfaces, like wires or metallic enclosures, generate unexpected current and electrical energy when exposed to electromagnetic waves that come from a wide variety of both natural and artificial sources. When electromagnetic energy disrupts the expected electrical performance of a device or material it’s called electromagnetic interference (EMI) or radio frequency interference (RFI) depending on the frequency spectrum of the interference. Uncontrolled natural and artificial energy waves enter or exit an electronic device through seams and openings in the device and cause erratic performance.
The Best Solution to Address EMI
The best solution to address EMI is a Faraday Cage, an enclosure around a device entirely made of continuous conductive material, unfortunately not feasible in product design. The next best solution is to design EMI shielding and absorption components in and around openings, gaps, and seams within a device to function as a barrier to unwanted external energy and contain internal electromagnetic waves.
