The electrodynamic characteristics of multirow interdigital slow wave structure

The results of an experimental study the dispersion characteristics and field distribution of main and higher order modes of multirow interdigital slow wave structures with their resized are presented. The ways of increasing the frequency separation of main and higher order modes and the working excitation band of the main mode are offered. Investigation the forced oscillations of the multirow interdigital slow wave structure with exponential $H$-waveguide power ports has shown the possibility of a single-mode excitation in a wide bandwidth. The results of an experimental study of the coupling impedance multirow interdigital slow wave structures with the use of the actual distribution of the longitudinal component of the electric field transverse (basic and higher) types of waves are presented. The estimation of the competitiveness of the worker and the parasitic waves types of multirow systems carried out by changing the position of the transverse waveguide screen.
