High power Terahertz generation by using vacuum electronic technology

With the fast development of Terahertz (THz) related technologies, more and more applications, such as high bandwidth communications, radar, and secure detection, which require higher power, more reliable THz radiation sources. There are different approaches to generate THz radiation. In this paper, we mainly focus on the vacuum electronic technology, which has the potential to provide a sufficient high power to facilitate a wide range of THz applications.
