Abstract :
The vane-loaded technology has been employed in TWTs to increase the bandwidth and output power. Here, we present a method to calculate the effect of the vane and supporting rod. We treat the vane-loaded helix as a series connection of the short section of the helical transmission line with different envelope radius and dielectric materials.
