Abstract：The sheet beam with a large width-high ratio is nonaxisymmetrical, which is very suitable to the formation of the electron beam in high power microwave and millimeter wave vacuum devices. In this paper, a 2D macroparticle model is proposed for developing a program to study the sheet beam transmission. The transmission of the sheet beam in an uniform magnetic field and Periodic Cusped Magnetic (PCM) field is discussed, and the calculation results are compared with the single particle model and 3D PIC software, which show good agreement with 3D PIC software’s and the computation time is greatly reduced.
