Mie Scattering by a Conducting Sphere Coated Uniaxial Single-Negative Medium

Mie Scattering by a Conducting Sphere Coated Uniaxial Single-Negative Medium

We propose an accurate analytical method to compute the electromagnetic scattering from three-dimensional (3D) conducting sphere coated uniaxial anisotropic single-negative (SNG) medium. Based on the spherical vector wave functions (SVWFs) in uniaxial anisotropic medium, the electromagnetic field in...
