Analysis of Two-dimensional Scattering by a Periodic Array of Conducting Cylinders Using the Method of Auxiliary Sources

A linear array constituted by a flnite number of conducting cylinders is modelled via the conventional method of auxiliary sources (MAS). Initially, the global coupling relating cylinders permits the near and far flelds calculation. Finally, taking into account partial coupling describing neighbouring cylinders leads to a partially fllled matrix, so therefore the computational cost is signiflcantly reduced. Global and partial coupling reveals the same results for the chosen arrays.
