根据磁绝缘线振荡器(magnetically insulated transmission line oscillator, MILO)中基模(TM00模)与临近高阶模(HEM11模)高频场分布的区别,采用破坏各腔之间HEM11模模谐振条件的方式抑制器件中高阶模产生的方法,提出了高阶模抑制型MILO. 运用三维全电磁粒子模拟软件对高阶模抑制型L波段MILO器件进行模拟研究, 数值模拟结果表面该方法能够抑制器件中HEM11模的产生.在此基础上对器件进行了对比性实验研究, 实验结果表明高阶模抑制型器件能够抑制HEM11模的产生,稳定工作在基模.A novel higher order mode depressed L-band magnetically insulated transmission line oscillator (MILO) device is put forward by destroying the-mode oscillating condition of HEM11 mode. High frequency analysis and PIC simulation are carried out. The simulation results reveal that the novel MILO device oscillates in TM00 mode and successfully suppresses the higher order HEM11 mode generation. Contrastive experiments are carried out. Purified 1.3 GHz microwave obtains a corresponding fundamental mode oscillation in higher order depressed MILO in contrast with original MILO which obtains a 1.42 GHz microwave output.
