Abstract
With the rapid development of modern electronic information engineering, electromagnetic interference (EMI) issues have become increasingly prominent, posing significant constraints on system performance and reliability. This study focuses on electromagnetic compatibility (EMC) design and optimization in electronic information engineering, aiming to address interference problems among devices in complex electromagnetic environments through theoretical analysis, experimental validation, and technological innovation. It begins by reviewing the fundamental principles of EMC and its current applications in electronic information engineering, identifying key challenges in present-day designs, such as spectrum resource scarcity, high-frequency signal interference, and the deterioration of electromagnetic environments due to miniaturization trends. To tackle these challenges, a multi-ob jective optimization-based EMC design scheme is proposed, integrating genetic algorithms with finite element simulation techniques to achieve comprehensive optimization of filter parameters, shielding structures, and grounding layouts. Additionally, for high-frequency EMI issues, novel absorptive materials are introduced, and their effectiveness in reducing radiated interference is experimentally validated. The results demonstrate that the proposed optimization method significantly enhances the EMC performance of systems, effectively reducing interference levels while ensuring functional implementation. Moreover, the scheme exhibits excellent adaptability and scalability, making it applicable to various types of electronic devices. The primary innovation of this research lies in combining multi-ob jective optimization theory with EMC design, proposing a systematic solution that is validated through practical case studies, thereby demonstrating its feasibility and superiority. This achievement not only provides new insights into EMC design in the field of electronic information engineering but also lays an important foundation for the development of future high-performance electronic systems.
