Abstract
With the rapid development of electronic information technology, electromagnetic interference has become increasingly prominent, severely affecting the stable operation and performance of electronic devices. To address this issue, this study focuses on electromagnetic shielding technology and its applications for electronic devices, aiming to explore efficient and reliable shielding solutions that meet modern requirements. By integrating theoretical analysis with experimental validation, the study systematically investigates the application potential of me tallic materials, composite materials, and novel nanomaterials in the field of electromagnetic shielding, while proposing optimized design strategies tailored to different scenarios. The results demonstrate that composite materials based on multi-layer structural designs significantly enhance shielding effectiveness, offering advantages of lightweight properties and reduced costs. Meanwhile, novel nanomaterials exhibit superior electromagnetic absorption capabilities, providing new directions for the development of high-performance shielding materials. A key innovation of this study lies in the proposal of a synergistic shielding mechanism that combines electromagnetic reflection and absorption, effectively resolving the issues of low efficiency and poor adaptability associated with traditional single-mode shielding approaches. Additionally, a comprehensive evaluation system for electromagnetic shielding performance under complex environments has been developed, offering scientific support for practical engineering applications. Overall, this study not only deepens the understanding of electromagnetic shielding technology but also provides critical technical support for the design and manufacturing of electronic devices, showcasing significant academic value and broad application prospects.
