Experimental Validation of Phase Velocity and Interaction Impedance of Meander-Line Slow-Wave Structures for Space Traveling-Wave Tubes

Juan M. Socuellamos et al.

Summary: Meander lines are considered promising slow-wave structures for millimeter-wave traveling-wave tubes due to their low-cost manufacture, low-voltage operation, and high interaction impedance. However, experimental results on meander lines are scarce in the literature. This article introduces a new experimental procedure based on a theoretical model to determine the phase velocity and interaction impedance of meander lines, which is validated on four different Ka-band meander-line SWSs, including two of a novel topology.
