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

Figure 3

Example of validation in near field: total equivalent current densities 𝐌^𝑖_1,tot, 𝐉^𝑖_1,tot, over a brick that embeds a dielectric sphere (not shown) in free space; (a), (c) results obtained with LEGO and PMCHWT; (b), (d) results obtained with LEGO and VIE (4). (See insets in Figure 4 for the surface and volumetric meshes of the sphere.) 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.
