摘　　要：超常材料具有人工设计的结构,并有自然材料所不具备的超常物理性质。超常材料的电磁响应灵活可调,对太赫兹(THz)技术意义非凡。THz超常材料的实现和迅速发展为太赫兹技术的发展和应用带来了新的机遇。总结了THz波段超常材料的研究进展,包括THz波段超常材料的构造及制备、基于超常材料的THz波器件以及超常材料在THz波技术中的其他应用。Metamaterials have artificially structured composite and novel electromagnetic properties not available in natural materials. The electromagnetic response of metamaterials can be tuned flexibly, and this is especially important for the terahertz （THz） technology. The realization and development of THz metamaterials provide an opportunity for the development and application of THz technology. The research progresses on the metamaterials at THz are summarized, including design, preparation, functional devices and other applications.
