双波纹波导（DCW），包括一排金属柱的电子束的两侧，被证明是一个有前途的慢波结构的毫米波，Ka波段，行波管（TWT）。不同的配置，包括新的弯曲耦合器与锥形柱，已被设计，实现，并验证了S参数测量。在32-37 GHz频段内，DCW行波管的设计和仿真结果表明，该行波管具有良好的性能。DCW易于制造和组装，使其成为新一代毫米波行波管的合适基础。
The double corrugated waveguide (DCW), incorporating a row of metallic pillars on each side of the electron beam, is demonstrated as a promising slow-wave structure for millimeter wave, Ka-band, traveling wave tubes (TWTs). Different configurations, including novel bent couplers with tapered pillars, have been designed, realized, and validated by S-parameter measurements. The design and simulation of a DCW TWT demonstrated very good performance in the frequency band 32-37 GHz. The ease of fabrication and assembly make the DCW a suitable basis for a new generation of millimeter wave TWTs.
