The objectives of the first stage are the rigorous substantiation of application of the domain-product technique to wave-scattering problems for waveguide transformers with loaded rectangular connecting cavities and the construction of generalized scattering matrices of dielectric filled triangular regions with attached wave channels for Dirichlet and Neumann boundary conditions on the conducting surfaces. At the second stage, the main goal is the modeling of different physical-mechanical fields, namely, monochromatic electromagnetic fields, fractal-inhomogeneous plasmoid and propagation of waves in rod-shaped structures. The objectives of the third stage are investigations of non-stationary deformations of constructional elements in corrosive medium. Research methods - projection methods for solution of boundary value problems for Helmholtz equation in domains with geometrically complicated boundaries; methods of integral transformations together with pliancy functions methods, which enable the study of stress-strain state in multilayered bodies with fractures; finite difference approach upon using of characteristics method applied to solution of resolving systems of differential equations and characteristic mapping of initial differential equations.
