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.
