Line Source Scattering by Buried Perfectly Conducting Circular Cylinders

Figure 3

Scattered far-field diagram of a perfectly conducting cylinder (𝛼=1, 𝜒=2.57, 𝜂=0, 𝑛₁=2, TM polarization) by a line source centred on 𝜂_𝐿=0, and placed at different positions 𝜒_𝐿; results are compared to the scattered field by a plane-wave excitation.
