Minghao Zhang,Yanyu Wei,Guo Guo,L. N. Yue,Yan Hou,Shaomeng Wang,J. Xu,Y.B. Gong,Wenxiang Wang +8 more
TL;DR: In this paper, a folded-wave guide (FWG) slow-wave structure with sheet-beam tunnel is presented for the high-power and considerable bandwidth in terahertz (THz) wave band.
Journal ArticleDOI
Development of a 140-GHz folded-waveguide traveling-wave tube in a relatively larger circular electron beam tunnel
Zhanliang Wang,Qing Zhou,Huarong Gong,J.X. Liao,Yanyu Wei,Zhaoyun Duan,Liu Hongwei,Yubin Gong +7 more
TL;DR: In this paper, a 140 GHz folded-waveguide traveling wave tube (FWG-TWT) with a relatively larger circular electron beam tunnel was designed and developed using simulation software, the high frequency characteristics, the transfer characteristics, and the beam-wave interaction of the TWT were studied in detail.
Journal ArticleDOI
Investigation of 0.38 THz backward-wave oscillator based on slotted sine waveguide and pencil electron beam
TL;DR: In this article, a backward wave oscillator was presented by utilizing a slotted sine waveguide with a pencil electron beam to produce the high power terahertz wave.
Journal ArticleDOI
Efficiency Improvement of Broadband Helix Traveling Wave Tubes Using Hybrid Phase Velocity Tapering Model
TL;DR: In this article, a hybrid phase velocity tapering model was proposed for a wideband (two-octave) vane-loaded helix traveling wave tube, of which the dispersion characteristic is anomalous over the operating frequency band.
Journal ArticleDOI
The Conditions for Stable Sheet Electron Beams Transport in Periodic Permanent Magnet Fields
Zhanliang Wang,Yubin Gong,Yanyu Wei,Zhaoyun Duan,Huarong Gong,Lingna Yue,Hairong Yin,Zhigang Lu,Jin Xu,Bei-ran Chen,Pu-Kun Liu,Gun-Sik Park +11 more
TL;DR: In this paper, a theoretical study and simulation on sheet beam transport in periodic permanent magnetic (PPM) fields is presented. And the three-dimensional simulations of the beam transport are in good agreement with the theoretical study.
