提出了隔模带相对论磁控管（Strapped RM）的设想并对其提高效率的机制进行了分析和粒子模拟验证.通过对比Strapped RM与传统A6模型发现：隔模带的采用能够显著改变互作用区的场分布以减小强高频场对注波互作用的影响,降低阳极电流以减小阳极表面的电子注能量损耗,从而提高管子效率.粒子模拟得到Strapped RM的效率超过了70%,有效克服了传统RM的低效率缺陷.

英文摘要：

Strapped relativistic magnetron（strapped RM） was proposed and its PIC simulation study was carried out.By comparing the strapped RM with the traditional A6 model,we observe that the use of straps can significantly change the distribution of field in the interaction region and reduce the harmful effect of the intense RF field to the beam wave interaction.It can also lower the anode current and reduce the energy loss of the electron beam on the surface of the anode.All these help to increase the efficiency of RM.By PIC simulation,the efficiency of strapped RM can be more than 70%.It effectively get rid of low efficiency which is the first shortcoming of RM.
