Abstract
- We have theoretically investigated the transport of a sheet electron beam focused by a uniform axial magnetic field in a metamaterial-loaded waveguide. A theoretical model has been proposed to analyze the sheet electron beam transport. In this model, we have used CST simulations to obtain the mean potential on the metamaterial as the boundary condition. According to the boundary condition, the space-charge electric field and the beam curling have been theoretically analyzed. It is found that the beam curling can be greatly reduced by decreasing the spacing between the metamaterial and the sheet electron beam. This model is verified using the CST simulations. This paper can pave the way for developing brand new metamaterial-based vacuum electron devices with a sheet electron beam. [ABSTRACT FROM AUTHOR]
