Electromagnetic Compatibility (EMC) refers to the ability of electronic equipment or systems to function properly in their electromagnetic environment without causing intolerable electromagnetic disturbance to anything in that environment.

EMC is divided into Electromagnetic Interference (EMI) and Electromagnetic Susceptibility (EMS).

With the rapid development of electronic technology, increased device integration, and expansion of operating frequencies into higher bands, the electromagnetic environment has become increasingly complex.

EMC issues have emerged as a critical bottleneck restricting the research, development, production, and application of electronic equipment. These issues may not only lead to performance degradation and functional abnormalities but can even cause safety incidents.
