Abstract
The impedance characteristic of folded-waveguide (FW) slow-wave structure (SWS) is studied in this paper. The impedance parameters are determined by the high-frequency parameters, especially the digital electromagnetic field data from a high-frequency structure simulator. After the analysis of the gap impedance of different radii and different angles, the formula of interaction impedance is presented. Finally, the coupling impedance is studied and compared with the interaction impedance. The method can be applied to other complex SWSs that lack of effective analytical methods.
