Figure 2. Scattering amplitude |f(θ)| in logarithmic scale for the soft object (ρ_s/ρ₀ = 0.1) with (a) k₀a_s = 0.1 and (b) k₀a_s = 1 and for the rigid object (ρ_s/ρ₀ = 10) with (d) k₀a_s = 0.1 and (e) k₀a_s = 1.

The dashed blue line represents the cloaked scenario whereas the solid red line stands for the bare object. Plots in (c) and (f) are the normalized backward scattering amplitude vs. k₀a_s for soft and rigid objects, respectively.
