The main attention in this paper is given to the representation of the field components on the conductive surface of the matching waveguide transition. This approach allows us to calculate the shape of the wave surface of the electromagnetic wave propagating in the irregular region and the transition transfer characteristics. The computational algorithm is based on the method of integral equations, which is based on one of the fundamental relations of electrodynamics, which is the integral form of the Lorentz lemma. The method of integral equations is applicable, both for calculating the dispersion characteristics of various irregular guiding structures, and for solving a wide range of internal diffraction problems of electrodynamics.
