A Novel Helical Slow-Wave Structure for Millimeter-Wave Traveling-Wave Tube
A novel helical slow-wave structure is proposed to develop wide-bandwidth, high-gain, high-power millimeter-wave traveling wave tube. This structure evolves from a conventional helical slow-wave structure with three parallel rectangular or other arbitrarily-shaped slots made in the outside of the helix. In this paper, the electromagnetic characteristics and thermal analysis of this structure are obtained using the finite-elementmethod. From our calculations, the novel and the conventional structure have similar dispersion characteristics, while the novel structure has higher heat dissipation capability than that of conventional one.
