界面电磁学的理论与应用

Theory and Applications of Surface Electromagnetics

近年来以超构表面(metasurface)为代表的各种新型电磁表面在微波、太赫兹、光学频段不断涌现,一个新的被称为“界面电磁学”的电磁学研究领域正在逐渐浮现。文章首先对界面电磁学做了一个概述,主要明确了其学科定位和研究框架。基于其研究框架,对界面电磁学的基础理论、表面设计和系统应用三个方面逐一进行了深入介绍。相信界面电磁学的系统深入研究将会给电子信息系统带来重大的影响和变革。

In recent years,new electromagnetic surfaces like metasurfaces have continuously emerged in microwave,terahertz,and optical bands,giving rise to a field named"surface electromagnetics."The article begins by offering an overview of surface electromagnetics,with a clear focus on defining its disciplinary scope and research framework.Based on the framework,we delve into three areas of surface electromagnetics:fundamental theory,surface design,and system applications.We believe that comprehensive research in surface electromagnetics will significantly influence and transform electronic information systems.
