Extended Linear Embedding via Green's Operators for Analyzing Wave Scattering from Anisotropic Bodies

Figure 4

Example of validation in far field: bistatic RCS of a dielectric sphere embedded in a cubic brick; (−) solution obtained through LEGO and PMCHWT [14], (∘) solution obtained through LEGO and VIE (14). Insets: surface and volumetric meshes of the sphere. (See Figure 3 for the surface of mesh of the cubic brick.) Data: brick’s edge 10 cm, sphere’s radius 4 cm, 𝜀₁=𝜀₂=𝜀₀, 𝜺₃=2𝜀₀𝐈, 𝐄^𝑖=𝐱exp(−𝑗2𝜋𝑓𝑧/𝑐₀) V/m, and 𝑓= 1 GHz.
