Scattering of a Plane Wave by an Anisotropic Plasma-Coated Conducting Sphere

Figure 2

Radar cross-sections (RCSs) versus scattering angle 𝜃 (in degrees): results of this paper (solid curve) and FE-BI-MLFMA method. The electric dimensions of the outer and inner spherical surfaces are chosen as 𝑘₀𝑎₁=1.3𝜋 and 𝑘₀𝑎₂=1.2𝜋 while the permittivity tensor elements of the plasma are assumed to be 𝜖₁=3𝜖₀, 𝜖₂=2𝑖𝜖₀, and 𝜖₃=4𝜖₀, respectively.
