太赫兹波导的研究进展

太赫兹(THz)有丰富的科学内涵和独特的优越特性,在物理、化学、电子信息、生命科学、材料科学、天文学、大气与环境监测、通讯雷达、国家安全与反恐等多个领域具有重要的应用前景。由于水汽对THz波的强烈吸收,适用于不同应用需求的THz波导成为急需。根据不同需求并考虑各种不同结构及材料波导特有的优势与缺陷,扬长避短选取合适的波导将有利于发挥THz科学技术在科学研究、生产、生活中的应用特色。该文对现有THz金属空腔波导、金属线波导、介质波导和其他THz波导的研究情况进行了综述,以期展现当前THz波导的研究情况,开拓研究思路。

Research Development of Terahertz Waveguides

There are rich scientific connotation and unique features in Terahertz (THz) spectrum, which lead to many important applications such as physics, chemistry, electric information, biomedicine, material science, astronomy, atmosphere and environment monitoring, communication and radar, national security and anti-terrorism, etc. THz waveguides suitable for different applications are urgent due to the strong vapor absorption of THz waves in the open air. Each THz waveguide has its most suitable applications according to its unique advantages and limitations, a rational choice will definitely facilitate the application of THz inscience research, manufactures, and lives efficiently. This paper presents an overview on research development of some typical waveguides such as THz metal cavity waveguides, metal wire waveguides, dielectric waveguides, and so on.
