Line Source Scattering by Buried Perfectly Conducting Circular Cylinders

Figure 6

Scattered near-field diagram of two perfectly conducting cylinders (𝛼₁=𝛼₂=1, 𝜒₁=𝜒₂=2.57, 𝜂₁=1.5,𝜂₂=−1.5, 𝑛₁=2, TM polarization) by a line source centred on 𝜂_𝐿=0 and 𝜒_𝐿=−0.5. Results are evaluated at the distance 𝜉=−1.
