## 5 Conclusions  
The problem of electromagnetic scattering by a group of stratified lossy dielectric cylinders enclosed in a cylindrical core which is surrounded by a boundless dielectric space was treated herein in the uttermost general instance of an arbitrarily polarized and obliquely incident plane wave. A boundary-value approach was employed, and the Bessel/Hankel function's translational addition theorem was applied, in order to form a group of linear equations for the unknown expansion coefficients of the scattered electromagnetic field intensity. The resulting solution may be considered as semi-analytical and exact since the only approximation used is the truncation of the multipole expansions. The validation of the developed computer codes was performed by checking the convergence of the solution and by carrying out extended comparisons with available published results, which were all successful. Plots of the total scattering cross section and the scattered far-field of various geometric configurations manifested how the structure and the material of the composite cylindrical model are imprinted on scattering.
