Introduction. The goals of the research presented in the paper are defined. The geometrical configurations of sectoral coaxial ridged waveguides are shown.
Cutoff wave numbers. The results of calculations of cutoff wave numbers multiplied by the outer radius of sectoral coaxial ridged waveguide with a ridge on an inner or outer wall obtained by transverse field-matching technique and integral equation technique are shown for the first four modes. The deviation between the results for cutoff wave numbers obtained by these two techniques is less than 0.5 %.
Solutions convergence for electric field components distributions. The convergence analysis of electric field components distributions depending on the amount of partial modes is carried out. It is shown, that for correct calculation of sectoral coaxial ridged waveguides field distributions by transverse field-matching technique one should utilize more than 30 partial modes.
Electric field components distributions. The electric field distributions in sectoral coaxial ridged waveguides of both configurations are investigated for the first four modes. All electric field components distributions computed by transverse field-matching technique are in good agreement with the ones obtained by integral equation technique with correct account of the singular field behavior at the ridge. This confirms the correctness of the results obtained.
Conclusions. General conclusions of the paper are given.
