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

Figure 5

Radar cross sections (RCSs) versus the thickness of the uniaxial SNG medium in the forward (solid curve) and in the back (dashed curve) directions, when inner radius is fixed at 𝑎₂=0.75𝜆. The parameters of the uniaxial SNG coating of the conducting sphere are assumed to be 𝜖_𝑡=−1.5𝜖₀, 𝜖_𝑡=−3𝜖₀, 𝜇_𝑡=3𝜇₀, and 𝜇_𝑧=1.5𝜇₀, respectively.
