Even algorithm for excitation equations of E0j-modes in irregular waweguides with circular section

摘要

The system of excitation equations of E0j — modes in the irregular waveguide with circular section is formulated in the even form (the first derivatives of amplitudes of E0j — modes in the core of the system are absent). This form of equations allows using of effective and convergence even algorithms for solutions. The effectiveness of suggested method is corroborated at series of examples of problem solutions for irregular waveguides with intense remarkable profiles.
