| Abstract: | To validate HFCS-I, a newly developed design tool for high frequency circuits of microwave tubes, the high-frequency parameters
(including dispersion, interaction impedance and attenuation constant) of a typical helical slow-wave structure (SWS) for
millimetre wave travelling-wave tube are calculated by HFCS-I and MAFIA. Both the direct calculation method and the Non-Resonant
Perturbation (NRP) technique are adopted to get the interaction impedance. The obtained high-frequency parameters from HFCS-I
and MAFIA are compared in detail and the consistency has proved the reliability and validity of HFCS-I. |
