Near field scattering by multiple infinite cylinders in an absorbing medium at oblique incidence

摘要

This paper presents the near field scattering formulation for an arbitrary configuration of closely spaced parallel infinite circular cylinders in an absorbing/magnetic medium at oblique incidence. No restriction is placed on the polarization of the incident plane wave, and complex permeability and refractive index are allowed for the cylinders and host medium. The electric and magnetic fields and Poynting vector of the scattered radiation are derived for both the near and far fields. Near field scattering by an assembly of cylinders at oblique incidence is illustrated for a transverse magnetic, transverse electric, and elliptically polarized source waves.
