摘要
随着电磁波干扰防护技术与隐身技术的的发展,吸波材料已成为科学研究的重要课题。介绍了材料的吸波原理、吸波材料的分类及其特征,总结了超材料吸波体在微波频段的应用研究现状,综述了超材料作为可调谐吸波体的研究进展,展望了超材料在可调谐吸波体中的研究趋势。
With the development of electromagnetic interference protection technique and military stealth technique, absorbing materials have become an important subject of scientific research. In this paper, the principle of metamaterial absorber as well as the classification of absorbing materials is introduced, and the progress of microwave metamaterial absorbers designed for microwave frequencies is outlined.Particularly, theoretic and experimental studies on tunable metamaterial absorbers are summarized, and the development trend of metamaterial in tunable absorbers is prospected.
