为了产生大功率连续太赫兹波，提出了一种可用于多通道双梳交错型慢波结构(SWS)。通过分析新型 SWS 色散特性和轴向场强分布特性，可知在不改变结构色散特性的情况下，增加结构通道数量可增大电子束电流，且结构在太赫兹频段具有较高电子效率。此外对该 SWS在300 GHz的注波互作用过程进行了粒子模拟，模拟结果显示，SWS 相邻2个通道在相同的工作条件下，输出功率增益均为20 dB，实现了多电子注有效并联的工作状态，从而使器件的输出功率得到提高。

A multi-beam double vane Slow-Wave Structure(SWS) with half-period-stagger is presented,which is used to generate Terahertz(THz) continuous and high power wave. By analyzing the cold dispersion characteristics and axial field distributions of the novel SWS,it indicates that increasing the number of sheet beams will increase the current of beam with the same cold dispersion characteristics, and the SWS shows a high electrical efficiency at high frequencies. The process of the beam-wave interaction of structure is simulated with PIC code at 300 GHz. The simulated results show that the power gains of adjacent channels are both 20 dB under identical operating conditions, which means this novel type of SWS can operate in parallel with multiple beams,therefore the output power of device can be increased.
