Numerical analysis of structure of an electromagnetic field in homogeneous dielectric waveguide structure

In letter the individual task solved within the framework of a common problem of the analysis of composite waveguide system, containing generally cascade connections of delguides with different parameters (as immediate, and through irregular ganging transitions) is considered. At solution the technique based on finite-difference approximating of secondkind equations with preliminary definition of amplitude-phase allocation of equivalent sources by methods of physical optics will be utilized effective, in sense computing time.
