Automatic Dispersion Measurements of Helical Slow- Wave Structure
AbstractAn experimental setup for computer-controlled automatic measurement of dispersion characteristi of helical slow-wave structures (SWSs) has been described. A non-resonant perturbation technique was employed for this purpose. The dispersion characteristics of a practical X-Ku band helical SWS
were studied using this experimental setup. The experimental results have shown good agreement with analytical results obtained using an equivalent circuit approach for an X-Ku band helix SWS.
