The matrix operator technique for modeling mode dinraction is presented. This approach was developed with B view to substantiate some modal expansion methods. It allows one to prove the correctness… (More)

The technique of the analytical justification of the matrix models developed via the eigenmode expansion methods (the mode-matching technique, the overlapping regions method, etc.) is proposed.… (More)

A novel full-wave solution of the problem of electromagnetic wave scattering by a circular post in a straight or continuously curved rectangular waveguide is presented. A rigorous mathematical model… (More)

The function of the second Lorentz theorem in deriving the operator form of the generalized power conservation law is considered. Some new forms of this law for the mode-diffraction problem are… (More)

A generalization of the conventional mode-matching technique, which corresponds to a new formulation of the problem of mode diffraction on the waveguide discontinuity, is proposed. To represent the… (More)

Recently, a new accurate and rigorous analytic-numerical analysis of guide bends has been carried out. The matrix model obtained is based on the spectral operator method. The approach developed… (More)
