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 flnite 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 flne-tuning the electric permittivity according to difierent geometries. The EMAS level of accuracy compared with the indirect matching mode method IMM reveals a good agreement between the numerical computation results.
