摘要
近距离无线通信技术的发展,对系统的安全性、稳定性提出了更高的要求。概述了近场通信(NFC)技术基本原理,分别从软磁屏蔽材料的作用、国内外研究状况、软磁材料表征方法以及NFC系统用软磁屏蔽材料的关键技术等方面,对这种材料进行了评述。文章还介绍了应用于甚高频段(UHF)NFC系统中的软磁材料研究状况。
Higher requirements in the stability and security of NFC systems were raised due to the development of NFC technology. The basic principle of NFC technology was summarized in this article. The rules of soft magnetic shielding materials, research status, characterization method of soft magnetic shielding materials, and key technologies were illustrated, respectively. The research status of soft shielding magnetic materials in the UHF systems was also introduced.
