摘要
在双频磁绝缘线振荡器的基础上,提出了多频磁绝缘线振荡器的设想,并利用电磁模拟软件,通过对磁绝缘线振荡器的高频结构进行优化,设计出了多频磁绝缘线振荡器。给出了能够同时稳定输出微波频率数目为1,2,3,4,5的多频磁绝缘线振荡器的粒子模拟结果。结果表明:多频磁绝缘线振荡器可以产生多个频率的高功率微波信号,其功率效率较单频磁绝缘线振荡器的功率效率有明显降低。
Based on the bifrequency magnetically insulated transmission line oscillator （BFMILO）, a multi-frequency mag netically insulated transmission line oscillator （MFMILO） was put forward. An MFMILO was designed based on the single-frequency MILO, and its high frequency-structure was optimized through electromagnetic simulation. According to different structure parameters, an MFMILO can generate high power microwaves with one-frequency, two-frequency, three-frequency, four-frequency and five-frequency. Simulation results show that an MFMILO can generate microwaves with multi-frequency, and their power efficiencies are less than that of single-frequency MILO. The reasons of less power efficiency are analyzed. The possibility to enhance the power efficiency and frequency quantity of output microwave is pointed out.
