摘　　要：太赫兹(THz)波在通信、成像、安全监测、生物医学等领域有着广阔的应用前景.随着THz技术的飞速发展,对其传输波导,特别是低损耗、单模、柔性传输等高性能THz波导的需求日益增长,这将为提高THz系统的灵活性及推动其实用化发展提供重要支撑.综述了金属膜波导和介质金属膜波导的设计和制备工艺,在0.1~0.3 THz和2.0~5.0 THz频段的损耗和单偏振单模传输等特性,以及在通信和成像等方面的应用.着重介绍了本课题组近年来在波导的设计、特性仿真、制备、测试和应用方面的研究结果.也对THz波导研制中存在的难点和发展前景进行了初步探讨.Terahertz(THz)waves have broad application prospects in fields such as communication,imaging,safety monitoring and biomedicine.With the rapid development of THz technology,the demands for its transmission waveguides,especially high-performance THz waveguides with low loss,single mode delivery and flexible transmission are increasing.This will provide important support for improving the flexibility of THz systems and promoting their practical development.We review the design and fabrication process of metallic waveguides and dielectric metallic waveguides,their characteristics of loss and single-polarization single-mode transmission in the frequency bands of 0.1‒0.3 THz and 2.0‒5.0 THz,as well as their applications in communication and imaging.We mainly focus on the research results of our research group in the design,characteristic simulation,fabrication,evaluation,and related applications of waveguides in recent years.And preliminary exploration is conducted on the difficulties and prospects in the development of THz waveguides.
