摘　　要：Metamaterial是一种新型的人工电磁材料,用Metamaterial制作的吸波材料具有体积小,重量轻,吸收效率高等特点。Metamaterial吸收材料的响应频率取决于其几何结构,可以通过缩比改变其工作频率。本文首先介绍了Metamaterial吸波材料的工作原理,并基于此原理介绍了Metamaterial吸波材料的设计方法,最后对国内外现有的THz波段的Metamaterial吸收材料的研究进行了总结。Metamaterial is a novel type of artificial electromagnetic material,and the absorbers made from metamaterial is small,light and can achieve near-unity absorption.The operational frequency of a absorber made from a given kind of metamaterial lies on its geometrical structure and can be geometrically scalable to other regimes of the electromagnetic spectra.In this paper,the work principle of the metamaterial absorber is introduced firstly,then its design method is presented.Lastly,the research status of THz band metamaterial absober are summarized.
