The aim is to construct an algorithm for solving the diffraction problem on the calculation of irregular areas of the waveguide path. The article offers a rigorous approach to the calculation of the transmission characteristics of smooth transitions between the two rectangular waveguides shielded misaligned different transverse dimensions. The article discusses the use of the method of integral equations for calculating the areas of the waveguide path in a smooth transition between the two waveguides same type (rectangular) cross-section with distinct axes (three-dimensional irregular structure). In this case the integral equations are based on the Lorentz lemma. The paper presents the formulation and solution of the diffraction problem of calculating a smooth transition between the two nesoosnoorientirovannymi rectangular waveguides of different transverse dimensions. The results obtained calculation module dependencies of the reflection coefficient and the passage of the fundamental wave of a rectangular waveguide H10 frequency coaxial connection with the waveguides, as well as the displacement of the axis of the second waveguide along the axes x, y and simultaneously along both axes of the coordinate system tied to the consideration of the guide structure.
