Method of calculation of a smooth transition between two round waveguides based on the integral ratio of Lorentz

In this work demonstrated a general approach to the calculation of the transmission characteristics of a smooth transition between the two waveguides of round cross-section. Method of calculation is based on the integral ratio of Lorentz. The purpose of the testing is a method for solving problems of the diffraction of electromagnetic waves on irregular sections of waveguide structures. Developed an algorithm the calculation of transmission characteristics of a smooth transition, connecting the guide structure of round cross-section. Shows the results the calculation of transmission characteristics of the track structure.
