A design study for a high-power, high-efficiency, high-growth-rate wideband traveling wave
tube (TWT) in W-band using a staggered double-vane slow-wave structure (SWS) combined …

We propose a new amplification regime based on a synchronous operation of four
degenerate electromagnetic (EM) modes in a slow-wave structure and the electron beam …

In vacuum electronics, the influence of the uniformity of electron beams on the performance
of two-or multi-beam devices is a key scientific problem in the development of compact, high …

Generally, it is difficult for the common backward wave oscillator (BWO) to produce powerful
THz radiation when the operating frequency increases to a high level such as over 1 THz …

At present, there is a great interest in increasing the power level of terahertz (THz) radiation
sources. Aimed to improve the output power of sheet electron-beam devices, a sub-THz …

Terahertz (THz) radiation obtained from the interaction between multiple sheet electron
beams and a backward wave operating in the high-order mode (HOM) provides an effective …

A planar distributed three-beam electron optics system with narrow beam separation is
investigated in this article for W-band fundamental-mode staggered double vane traveling …

A slow-wave structure named coupled double folded waveguide (CDFW) is proposed for
traveling wave tube operating at terahertz region. Its electromagnetic characteristics and …

The parameters for a kilowatt-level high-power terahertz amplifier were explored based on
the higher-order mode and extended-interaction mechanism. It has been demonstrated that …

In comparison to single-sheet electron beam devices, the output power of multiple-sheet
electron beam devices is hopeful to be significantly enhanced due to the increased beam …
