Research Progresses of Millimeter and Terahertz Waves Traveling Wave Tube in AIRCAS

The Terahertz (THz) traveling wave tube (TWT) is developed for demands of broad applications, such as broad bandwidth communications, biomedicine, security check, basic subject research, etc. Through solved and grasped key technologies of THz TWT, some THz TWTs has been designed, fabricated and measured at frequency W-band, G-band and J-band. In this paper, the research progresses of THz TWT in Aerospace Information Research Institute, Chinese Academy of Sciences (AIRCAS) will be described.
