Abstract

The theoretical formulation for the scattering of electromagnetic waves by a finite configuration of closely spaced parallel nonhomogeneous infinite circular cylinders in an absorbing/magnetic medium is presented in this paper. The source radiation is an arbitrarily polarized plane wave propagating in a general direction at the cylinders. Each circular cylinder is radially stratified with an arbitrary number of layers, and the refractive index and magnetic permeability in each layer are distinct. The refractive index and permeability of the host medium and cylinders are in general complex. Closed form solutions are derived for the extinction and scattering cross sections and scat tering intensity distribution in the far field. Numerical results on the scattering properties of a specific configuration of coated cylinders in an absorbing/magnetic medium are presented for the purpose of illustration.
