宽带太赫兹波在大气中的远程探测研究及展望

Broadband long-path THz pulse transmission through the atmosphere

  • 摘要: 宽带太赫兹波由于具有传输容量大、速率高、方向性好、安全性高、散射小及穿透性好等许多特性,使太赫兹技术在高保密卫星通信、短距离无线通信等方面具有独特的优势。但是,如何克服大气中水蒸气的强吸收,找出适合太赫兹通信的频段,是发展宽带太赫兹远程传输亟待解决的问题。文章介绍了宽带太赫兹波在大气中远程探测的一些关键技术和最新研究成果,同时,对太赫兹通信技术的发展趋势和应用前景作了展望。

     

    Abstract: Broad band THz radiation has great protential application in wireless communications due to the following features: high data transfer rate, good directionality, high safety, low scattering,high transmittance, and so on. However, many technical problems, such as how to avoid absorption by water vapor and finding the most promising windows of transparency, need to be resolved. In this paper we review several key techniques and latest achievements in the research on long-path THz transmission through the atmosphere. Future trends and application prospects are also discussed.
