Abstract
With the rapid development of modern technology, the widespread use of electronic equipment makes electromagnetic interference (EMI) problems intensify, electromagnetic compatibility (EMC) is increasingly important. This article first describes the basic concepts of EMI and EMC. The generation and propagation mechanism of EMI are specifically introduced. It reviews the development history of EMC, from the early simple shielding method to today's multi-layer shielding, high-performance filtering and other complex technologies. Then discuss its applications in wireless communications, such as building models to solve RF desensitization, addressing EMI challenges in OAM mode communications, and conducting EMC analysis of 5G technology to help spectrum management. In the field of new energy vehicles, EMC also plays an important application in ensuring safety. Finally, it discusses the current EMC and EMI challenges such as spectrum tension and interference in wireless systems and introduces the latest research results such as new modulation techniques and signal processing methods. In conclusion, this article comprehensively analyses EMC and EMI related contents, and systematically summarizes some research results from the main developments and applications in recent years, providing a reference for dealing with related issues.
