Analysis of Two-dimensional Scattering by a Finite Periodic Array of Conducting Cylinders Using the Method of Auziliary Sources
According to the method of auxiliary sources and for conducting bodies, the scat-tered field is the summation of radiated fields by a set of auxiliary sources distributed on a fictitious inner contour near the physical one and satisfying the Helmoltz equation outside the considered domain 3. The satisfaction of boundary conditions leads to the unknown complex currents. The MAS applied to model coupling between a finite array of infinitely and parallel conducting cylinders, illuminated by a monochromatic plane wave. The coupling modeled by the mutual satisfaction of the boundary conditions just on the collocation points of every cylinder 6. In the purpose to decrease the computational cost and to alleviate calculus, we suppose that every cylinder is coupled only to the eight neighbouring cylinders. The partial coupling implementation full simplifies the global matrix expression. The comparison between the results obtained (RCS, field pattern) according to global and partial coupling for the same array reveals good agreement with references. In this paper, we validate the MAS applicability for the global coupling and the approximation validity for the partial coupling for a finite array of conducting cylinders.
