| Abstract: | The stable focusing or transport of sheet electron beams is an essential technology for an emerging class of high-power high-frequency planar-structure microwave devices. This paper, in consideration of space-charge field and cyclotron motion, describes theoretical study and simulation on sheet beams transport in periodic permanent magnetic (PPM) fields. Based on the theoretical study, we obtain the clear conditions for the stable sheet beams transport in PPM field. And the three-dimensional simulations of the sheet beam transport are in good agreement with our theoretical study. Our research will be useful in further study and experimental. |
