PROJECT TITLE :
Double Corrugated Waveguide for Ka-Band Traveling Wave Tube
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 planning and simulation of a DCW TWT demonstrated terribly good performance in the frequency band thirty two-37 GHz. The ease of fabrication and assembly create the DCW a suitable basis for a brand new generation of millimeter wave TWTs.
