The sheet beam vacuum electron device is an attractive choice for generating high-power high-frequency microwave radiation. A millimeter-wave sheet beam backward wave oscillator (BWO) is presented in this paper. The rectangular waveguide grating structure is used as its slow wave structure. The BWO is driven by a sheet beam with a cross-sectional area of 30 mm 1 mm which is generated by a thin...
Stable high-elliptical sheet electron beam transport is an essential technology for an emerging class of high-power high-frequency planar-structure microwave devices. This paper studies on stable sheet beam transport in elliptical solenoid field. First, we investigate the magnetic field of elliptical solenoid. Then, we use 3D PIC simulations investigate the sheet beam transport in the elliptical magnetic...
