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

Figure 4

Radar cross-sections (RCSs) versus scattering angle 𝜃 (in degrees) in the 𝐸 -plane (solid curve) and in the 𝐻 -plane (dashed curve). The electric dimensions of the outer and inner spherical surfaces are chosen as 𝑘 0 𝑎 1 = 2 𝜋 and 𝑘 0 𝑎 2 = 𝜋 while the permittivity tensor elements of the plasma are assumed to be 𝜖 1 = ( 7 + 0 . 2 𝑖 ) 𝜖 0 , 𝜖 2 = 𝑖 𝜖 0 , and 𝜖 3 = ( 5 + 0 . 1 𝑖 ) 𝜖 0 , respectively.
