摘　　要：　为了进一步提高MILO产生微波的功率和效率,提出了其负载电流能量全部利用来产生微波的新思想。设计并运用二维全电磁PIC方法模拟了基于此思想的新型MILO,它是传统MILO与VCO的有机结合(简称MVO)。模拟结果表明MVO中MILO部分与作为MILO负载的VCO部分各自工作正常,VCO部分产生微波的主频受MILO部分产生微波的牵引。在输入25GW电功率(工作电压约500kV)下,与相应传统MILO相比,MVO的微波平均输出功率提高了500MW,效率从6%提高到了8%。In order to essentially improve microwave output power and efficiency, a new idea about magnetically insulated transmission line oscillator (MILO) is brought forward, which use most of the load current to produce microwave. A new type of MILO that comprises traditional MILO and VCO, called MVO, is designed and simulated by 2D PIC method. The results show that both parts of MVO work well and the main frequency accords with slowwave structure (SWS), and that MVO yields an output power of 500MW higher than traditional MILO in the case of 25GW(at 500kV) inputpower with the efficiency enhanced from 6% to 8%.
