GENERALIZED MODE-MATCHING TECHNIQUE IN THE THEORY OF GUIDED WAVE DIFFRACTION. PART 1: FRESNEL FORMULAS FOR SCATTERING OPERATORS
RÉSUMÉ
A generalization of the conventional mode-matching technique corresponding to a new formulation of the problem of wave diffraction by waveguide discontinuities is presented. The matrix-operator formalism used in the study for the modal analysis is briefly described. Fresnel formulas are derived for the sought-for operators of mode reflection and transmission in the canonical problem of step discontinuity in the guide. The correctness of the found matrix-operator model is proved analytically. It is shown that the obtained results are valid for a wide class of scalar problems of wave diffraction by step-like discontinuities in the waveguide. The developed generalization of the mode-matching technique is intended for efficient and rigorous analysis of waveguide units and microwave devices.
