The peculiarities of approximate solutions of vector electrodynamic problems in both cases are discussed. The offered methods are applicable for analysis of similar dielectric, magnetic, optic and meta materials structures in enough broad band of electromagnetic wavelengths.

The graphs of the dispersion relations of the TE and TM modes of the regular planar integrated-optical waveguide, graphics of fields of radiative TE modes of the substrate and graphics of fields of electromagnetic radiation scattered in an irregular three-dimensional integrated optical waveguide are presented.

The peculiarities of approximate solutions of vector electrodynamic problems in the first cases in brief are discussed and useful evaluations of losses due to scattering also are given. Some results of research of radiation losses of optical nanofibers in assumption of Gaussian statistics of distorted glass/air interface are presented. In conclusion we mark a problem of synthesizing of an optical processor or/and optical sensor with high metrological parameters with allowance for the problem of light scattering in optical waveguides with surface roughness.
