文摘An all-metal slow-wave structure, coaxial-radial line, which is suitable for application in broadband high power traveling wave tube (TWT) and relativistic TWT as a RF system is introduced. Making use of the field matching method and variational method together with the orthogonality of the Bessel function and the Floquet Theroem for the periodic system, the dispersion characteristic expression is derived. This equation is more rigorous than that of precious reports.
