摘要
随着现代科技的进步,人们对电子设备高速运行的需求使电子元器件正向轻量化、微型化、集成化方向发展。不同电子设备运行中产生的电磁干扰(EMI,Electromagnetic interference)会对电子系统性能产生不利影响,长时间暴露在电磁辐射下也会对人体健康造成危害。因此,抑制或减缓不良电磁干扰已成为材料科学领域的重要研究方向。本文简要介绍不同电磁屏蔽材料的特性、组成及屏蔽机理,综述了国内外电磁屏蔽技术的研究与应用。
With the progress of modern science and technology,demands for high⁃speed operation of electronic equipment make electronic devices develop in the direction of lightweight,miniaturization and integration.Electromagnetic interference(EMI)generated by different devices adversely affects the performance of electronic system,and human health may be harmed after long time exposure to electromagnetic radiation.Therefore,the suppression or mitigation of undesirable electromagnetic interference has become an important research direction in the field of materials science.In this review,characteristics,composition and shielding mechanism of different electromagnetic shielding materials,and research progress and applications of electromagnetic shielding technology are summarized.
