SCATTERING OF OBLIQUELY INCIDENT PLANE WAVE BY AN ARRAY OF PARALLEL CONCENTRIC METAMATERIAL CYLINDERSBy B. H. Henin, M. H. Al Sharkawy, and A. Z. ElsherbeniAbstract: A rigorous semi-analytical solution is presented for electromagnetic scattering from an array of parallel-coated circular cylinders of arbitrary radii and positions due to an obliquely incident TMz plane wave excitation. In order to check the validity of this technique, the radar cross-section of a single coated cylinder, a linear array of cylinders, and an arbitrary position array of cylinders are calculated and compared with available data in the literature. Furthermore, the near field is calculated to prove the validity of the boundary conditions on the surface of any cylinder with obliquely incidence wave. As an application, circular metamaterial cylinders are used to show the effect of metamaterial characteristics in altering the forward and backward scattering and in focusing the near field around the objects.
