“…Cylindrical geometries are typically much more stable and can be easily controlled by means of conventional periodic permanent magnets, but the results for gain and output power are very discrete [6]. Even though different efforts have been made in order to increase the output levels using cylindrical electron beams [7,8], the results are not yet satisfactory for satellite applications at W-band and better configurations are necessary. This paper presents a three-dimensional meander line structure which has been shown to provide much better results than a planar meander line of the same characteristics.…”

Planar meander lines have been recently studied in detail due to their favorable properties as slow wave structures for traveling wave tubes. However, the interaction of a cylindrical electron beam with this kind of structures is not efficient enough in order to achieve the output power levels required for space applications at Wband. A new design, suitable and optimized for the cylindrical beam geometry, is introduced in this work. Cold and large signal results are presented in the paper.
