Bilateral dielectric rod clamping dual-electron-beam periodic zigzag metal wire slow-wave structure

The invention discloses a bilateral dielectric rod clamping dual-electron-beam periodic zigzag metal wire slow-wave structure, and relates to the field of a planar traveling wave tube slow-wave structure. The bilateral dielectric rod clamping dual-electron-beam periodic zigzag metal wire slow-wave structure comprises a metal cavity, a cathode electron emitter welded at one end of the metal cavityand a slow-wave structure body arranged on the metal cavity, the slow-wave structure body comprises a metal wire, dielectric rods arranged at two sides of the metal wire respectively for fixation andan attenuator arranged at the middle of the dielectric rods, both ends of the metal wire are provided with a gradually changing section, each gradually changing section is communicated with the internal part of the metal cavity and externally forms a coaxial interface, the metal wire adopts a uniformly periodic zigzag metal wire, and the metal wire is connected end to end in a in a shape like a Chinese character 'ji'.
