Abstract

With the increasing operating frequency and integration level of electronic devices, electromagnetic compatibility has become a key factor affecting system stability and performance. Sources of electromagnetic interference are widespread, including the impact of complex external electromagnetic environments as well as coupling effects of high-speed signals and power noise within devices. To improve electromagnetic compatibility, systematic optimization is required across multiple aspects including circuit design, PCB layout, structural shielding, and simulation analysis. The development of emerging technologies is further driving electromagnetic compatibility design toward intelligent and high-precision directions, providing new solutions to address future challenges in electromagnetic environments.
