  • 推导了双频磁绝缘线振荡器(BFMILO)慢波结构的本征方程,并研究了其色散特性和场分布.通过研究发现,通过引入角向分区,使BFMILO慢波结构表现出二维周期性的特点,在该慢波结构中,不同电磁模式集中在角向不同区域,传统磁绝缘线振荡器(MILO)中呈现竞争关系的两个不同电磁模式可以同时独立稳定地参与束-波换能,从而产生双频输出.该分析方法可以适用于多频磁绝缘线振荡器的研究.
    The eigen function of a bifrequency magnetically insulated transmission line oscillator (BFMILO) is deduced, and the dispersion characteristics and the field distribution are analyzed in detail. By dividing a traditional symmetrical coaxial disk loaded slow wave structures (SWS) into two different azimuthal partitions, the SWS of BFMILO becomes a two-dimensional SWS. In this structure, different electromagnetic modes are distributed in different azimuthal partitions, so that two different electromagnetic modes, which are competition modes in a traditional MILO, can interact with electrons separately and stably. This special SWS is the key point in designing a BFMILO. The proposed method can also be used in analyzing a mlti-frequency MILO.
