EE 423 Electromagnetic Compatibility
Electromagnetic devices exchange energy by means of conduction currents, inductive effects, and electromagnetic radiation. Generally, the specifics of this exchange are integral part of the design of devices intended to operate as components of a larger system. However, additional exchanges of energy may occur among devices during their normal operation, which were not intended in the original design. These effects may lead to a distortion or degradation of a device's performance, or even to irreversible damage. Another, more sinister, concern with such unwanted energy exchanges is that the undesired energy emanating from a device constitutes a signal, which can potentially be captured by a resourceful agent and exploited to eavesdrop on sensitive communications. Such malicious activities are known as side-channel attacks, and pose a major cybersecurity threat. Electromagnetic Compatibility (EMC) is the modern term, which has largely supplanted Electromagnetic Interference (EMI), used to designate the study of all effects related to the unintended energy/signal exchanges between devices or parts of a single device, and the design strategies aimed at minimizing or preventing such effects.
