Abstract
Some new ideas for vacuum electron devices are introduced and commented in this paper.As millimeter wave (mmW) and terahertz (THz) technique developing,the requirements for vacuum electron devices such as high frequency,high power output,wide bandwidth,high efficiency and micro-fabrication are increased.The sheet beam and multi-beam array are important ways to increase the device power output;the photonic band gap (PBG) combined with vacuum electronics will provide an approach to new device;ceramic structure TWT is a new concept for vacuum electron device;especially the metal-oxide-semiconductor field-effect transistor with a vacuum channel and vacuum electron-based photodiode concept proposals hopefully may bring vacuum electronics returning to numerical electronics.关键词
