摘　　要：为了对中美超材料基础科学研究态势和前沿热点进行对比,为国家科技计划项目规划和科学研究决策提供支撑,本文基于SCIE收录的2000—2022年中美超材料相关论文,采用文献计量方法,借助DDA和VOSviewer数据处理和分析软件,从论文产出、论文被引、资助机构、主要机构和学者、技术主题和热点前沿等角度进行对比分析。研究表明,中国正在成为全球超材料领域的主导国家,发文量于2012年超过美国后居全球第一,论文的篇均被引数正在赶上美国;美国从2018年开始发文量呈逐年减少趋势。“太赫兹”长期占据中国超材料研究主题的主导地位,近5年“超表面、声和机械超材料、超材料吸收器”等相关研究热度提升,研究主题更加多样化;美国近5年的研究热点则是“超表面、机械超材料、双曲超材料”等。建议我国政府的资助重点向“超表面、拓扑优化和制造、深度学习”等前沿热点和跨学科领域倾斜,借助“信息超材料”等领先领域的带动,提升国际合作力度和全球影响力。In order to support the national science and technology plan and scientific research decision-making,the trends and frontiers of metamaterials basic research in China and the United States are compared and analyzed.Based on the papers retrieved from the SCIE database between 2000 to 2022,a comparative analysis between China and the United States from the aspects of paper output,citations,funding institutions,top research institutions and scholars,as well as research hot spots by using the method of bibliometrics,and with the help of data analysis software DDA and VOSviewer.It has been found that China is becoming a global leader in the field of metamaterials,after surpassing the United States in 2012,the publications in the field of metamaterials of China has climbed to the top in the world,and the citations rates is catching up with the United States in recent years.The number of publications of the United States has been decreasing year by year since 2018.China has been fascinated by Terahertz for a long time,the publications of China on Metasurfaces,Acoustic and Mechanical Metamaterials,and Metamaterial Absorbers has increased significantly,and research topics are more and more diversified in the past five years.At the same time,Metasurfaces,Mechanical Metamaterials,and Hyperbolic Metamaterials have been the hot topics in the United States.It is suggested that our government should provide more financial support to frontier hotspots and interdisciplinary fields such as Metasurfaces,Topology Optimization and Fabrication,and Deep Learning.Moreover,enhance international cooperation and global influence by advancing the most prominent fields of Information Metamaterials and other disciplines.
