A novel ridge-loaded staggered single-slot rectangular coupled-cavity traveling-wave tube (CC-TWT) operating at $X$ -band is presented. It features large interaction impedance and good thermal dissipation with a moderate bandwidth. Compared with the existing staggered single-slot rectangular CC-TWT and Hughes-type TWT, this structure has the advantage of large coupled impedance and high electron...
The analysis of the novel coupled-cavity traveling-wave tube(CC-TWT) operating at X-band is presented for the purpose of gaining higher power with a smaller size compared with the existing coupled cavity circuit. The electromagnetic characteristics, and the beamwave interaction based on the ridge-loaded staggered single-slot rectangular coupled-cavity slow-wave structure(SWS) are investigated. Compared...
A novel slow wave structure (SWS) called sine ridge waveguide (SRWG) has been proposed for a wideband high-power terahertz radiation source. The cold bandwidth of the SRWG is similar to the sine waveguide structure. Meanwhile, the interaction impedance of the SRWG is about 70% higher than sine waveguide at 0.65THz with the same dimensional parameters. Furthermore, it possesses low ohmic losses and...
