| 摘 要： | 采用平面对数螺旋线慢波结构可以有效减慢电磁波的相速，电子注的加速电压可低至百伏量级。利用仿真软件HFSS，对20~40GHz 频段的平面对数螺旋线的色散、同步、损耗和传播特性及它们与结构尺寸的关系进行了仿真分析。结果表明，选择适当的慢波结构尺寸，得到的色散曲线较平缓；衰减较小，慢波结构中电磁波与电子流的作用效率比较高；具有较好的传播特性。

| Abstract: | The planer logarithm spiral slow wave circuit can effectively reduce the phase velocity of radial electromagnetic wave. For such slow phase velocity, the accelerating voltage can be as low as hundreds volts. Using electromagnetic simulation software HFSS, simulation of dispersion, synchronization, attenuation, transition characteristics of the planner logarithm spiral slow wave circuit and its relationship with the structure at 20~40GHz were carried out. By choosing appropriate slow wave structure, the dispersion curve is gently smooth. Attenuation is relatively small, the electron beam and the electromagnetic wave interact effectively. have a well propagation character. |
