Extraordinary Electromagnetic Scattering of Plane Wave by Double Negative Coated Sphere
Based on generalized Lorenz-Mie theory and Ricatti-Bessel Derivation functions,a theoretical analysis of electromagnetic scattering of a plane wave by an isotropic sphere coated by double negative metamaterial (DNM) is investigated.The extraordinary scattering characteristic of an isotropic sphere coated by DNM is numerically discussed,which is different from those by double positive material (DPM).The effects of the refractive index of inner sphere material and core-shell ratio on the scattered intensity and degree of polarization are numerically studied and analyzed.
