太赫兹波(Terahertz。THz)是指频率在0.1—10THz或波长为30μm-3mm范围内的电磁波。THz频段是一个非常具有科学价值但尚未完全开发的电磁辐射区域,它在成像、医学诊断、环境科学、信息通信、生物化学及基础物理研究领域有着广阔的应用前景。本文综述了THz波的特点、发展状况,重点介绍了THz技术的应用领域,简单阐述了THz技术的发展方向及存在问题,并讨论了其发展前景。
Terahertz(THz) radiation lies between far-infrared and microwave in electromagnetic spectrmn with frequency from 0.1 to 10 THz. In this paper, a review was given to summarize the unique properties, the progress of THz wave and the problems existed to introduce the applications of THz wave in detail.
