Analysis of Scattering from a Finite Linear Array of Dielectric Cylinders Using the Method of Auziliary Sources
The numerical analysis, in the order to approximate scattered fields by larger bodies, is limited by the allowed computational cost and memory needs. The method of auxiliary sources is exploited to model the scattering properties from a finite linear array of dielectric cylinders taking into account the coupling between the different cylinders 3. According to the MAS and for each dielectric cylinder, two bases of auxiliary sources must be considered; the first one distributed outside the physical contour and acts inside, the second is inside and acts outside 1. The coupling modeled by the mutual satisfaction of the boundary conditions involving the con-tinuity of the tangential field components just on the collocation points of every cylinder 2. In the aforementioned global coupling model, we implement the fact that every cylinder is coupled only to the neighbouring cylinders (partial coupling), the linear system matrix in fully simplified entraining a significant decrease in the computational cost and memory requirements. According to the global and partial coupling, numerical results (RCS, pattern field) reveal good agreement with references.
