基于电子学的太赫兹辐射源

Terahertz radiation sources based on electronics

随着太赫兹科学与技术的发展,太赫兹辐射源研究受到越来越广泛的重视.本文对近年来常见的基于电子学的太赫兹辐射源进行综述,包括基于新型慢波结构真空电子器件的仿真设计与实验结果、基于电子回旋谐振脉塞的太赫兹辐射源和基于史密斯-帕塞尔效应的太赫兹辐射源的国内外研究近况,以及基于类等离子体光子晶体的太赫兹辐射源和固态太赫兹辐射源.对太赫兹辐射源在无线通信、成像探测、光谱探测和生物医学等方面的应用进行了展望.

With the development of terahertz (THz) science and technology,THz radiation sources are studied extensively.In order to understand and grasp the research progress of the domestic and international research progress of the THz radiation sources in the recent years,this paper summarizes the THz radiation sources based on electronics,and gives some experimental and simulation results of vacuum electron devices based on the novel slow wave structure.This review also summarizes the domestic and international research progress of THz radiation sources based on electron cyclotron resonance maser, Smith-Purcell,plasma photonic crystal-like beam-plasma system and solid-state devices in the recent years.In addition,this paper presents the outlook of applications of the terahertz radiation sources in the field of wireless communication,imaging detection,spectral analysis and biomedicine.
