Journal ArticleDOI
A Novel V-Shaped Microstrip Meander-Line Slow-Wave Structure for W-band MMPM
TL;DR: In this article, a V-shaped microstrip meander-line slow-wave structure was proposed for use in a lowvoltage high-efficiency widebandwidth miniature millimeter-wave traveling-wave tube (TWT).
Journal ArticleDOI
W-Band 1-kW Staggered Double-Vane Traveling-Wave Tube
TL;DR: In this article, a W-band traveling-wave tube (TWT) with a staggered double-vane slow-wave structure combined with a sheet electron beam was designed to achieve an output power of over 1 kW.
Journal ArticleDOI
A 140-GHz Two-Beam Overmoded Folded-Waveguide Traveling-Wave Tube
TL;DR: In this article, a folded-waveguide traveling-wave tube (TWT) with two electron beams, which operates at the higher order mode, is simulated and shown to be unstable if the gain per section is over 11 dB, because both fundamental and band-edge modes are strongly excited.
Journal ArticleDOI
