Abstract-This paper establishes the extension of the method of auxiliary sources EMAS for the purpose of modeling the electromagnetic scattering response by jacket cylindrical structures constituted by a finite number of dielectric eccentric cylindrical inclusions embedded in a host dielectric one. Appropriate boundary conditions mixed with judicious decomposed domains leads to the prediction of the backscattering cross section. The algorithm also integrates the global electromagnetic coupling between the inclusions. The EMAS is validated by varying the inner cylinders repartitions and fine-tuning the electric permittivity according to different geometries. The EMAS level of accuracy compared with the indirect matching mode method IMM reveals a good agreement between the numerical computation results.

Abstract-A volume-surface integral equation (VSIE) formulation is developed for determining the electromagnetic TM scattering by a two-dimensional conducting cylinder coated with an inhomogeneous dielectric/magnetic material. The electric field integral equations (EFIEs) are utilized to derive the VSIE. The surface EFIE is applied to the conducting surface, while the volume EFIE is applied to the coating region. By employing the surface and equivalence principles, the problem is reduced into a set of coupled integral equations in terms of equivalent electric and magnetic currents radiating into unbounded space. The moment method is used to solve the integral equations. Numerical results for the bistatic radar cross section for different structures are presented. The well-known exact series-solution for a conducting circular cylinder coated with multilayers of homogeneous materials is used along with the available published data to validate the results. The influence of using coatings with double-positive (DPS) and/or double-negative (DNG) materials on the radar cross section is investigated.

“…Considerable discrepancies exist in the difficulty of numerically evaluating of the different models. [1][2][3][4][5] The study of absorption properties for some threedimensional models of man is interesting in practice, but in most of the real cases an exact calculation by analytical methods is impossible. Generally, the real models are approached with numerical techniques -finite differences, moment's method, finite element, etc.…”

This paper is intended to give a simple electromagnetic formulation of the EM power absorption properties of multi -layered cylindrical model of man at RF frequencies and above. The formulation, however, has no limitations concerning frequency. Thus very low frequencies are also considered for comparison with the results in literature. Both horizontal and vertical polarizations are considered. A single general expression for model of man has been derived.Absorbed power density of man against different values of incident power are illustrated at different frequencies and compared with ICNIRP standards.
