Slow-wave characteristics of a broadband `semi-vane' helical SWS have been studied using 3D electromagnetic modeling in CST-studio. The geometry has shown promises for better broadbanding potential compared to a conventional segment loaded configuration. Also, the results have shown that placement of segments closer to the support rods provides a better negative dispersion.
A simple equivalent circuit analysis of the ring-bar slow-wave structure of a traveling-wave tube is developed, using the coupled transmission-line approach, for the dispersion and interaction-impedance characteristics of the structure. The effects of the ring and the bar widths of the structure are included in the analysis. The analysis is validated, with respect to 1) an X-band structure, against...
The effect of inhomogeneous dispersion shaping of a helical SWS on the backward-wave has been studied. Theoretical simulations of three types of dispersion, namely, positive, flat and negative, achieved in an inhomogeneous structure and the interaction impedance characteristics thereof were carried out. The analysis of backward-wave oscillation criterion has been carried out to assess the effects...
