Abstract

DIMOHA is a many-particle time-domain model offering a good balance between exhaustive physics and time efficiency. We apply this model to study the effects of defects and reflections in the slow wave structure (SWS) of a traveling wave tube (TWT). To assess DIMOHA’s validity, we set up a TWT with varying reflection coefficients at the tube’s end. A ripple effect in saturated output power with respect to frequency is measured and simulated self-consistently with a rough agreement.

行波管反射：一维时域哈密顿模型DIMOHA的模拟与实验验证

DIMOHA是一个多粒子时域模型，在详尽物理和时间效率之间提供了很好的平衡。应用该模型研究了行波管慢波结构中缺陷和反射的影响。为了评估DIMOHA的有效性，我们在管的末端设置了不同反射系数的行波管。对饱和输出功率的纹波效应与频率的关系进行了测量和模拟，结果自一致，大致一致。

期刊介绍： IEEE Transactions on Electron Devices publishes original and significant contributions relating to the theory, modeling, design, performance and reliability of electron and ion integrated circuit devices and interconnects, involving insulators, metals, organic materials, micro-plasmas, semiconductors, quantum-effect structures, vacuum devices, and emerging materials with applications in bioelectronics, biomedical electronics, computation, communications, displays, microelectromechanics, imaging, micro-actuators, nanoelectronics, optoelectronics, photovoltaics, power ICs and micro-sensors. Tutorial and review papers on these subjects are also published and occasional special issues appear to present a collection of papers which treat particular areas in more depth and breadth.
