Figure 5. Time-averaged displacement field distributions (vector direction with white arrows, amplitude indicated by the contours) in linear scale of a rigid elastic object with ρ_s/ρ₀ = 10 cloaked by a Drude-like shell (a) and on its own for comparison (b).

The structures are illuminated with a unit-amplitude plane wave (k₀a_s = 0.11) propagating in the x-direction from right to left.
