Measured transient response for the structural wave cloak and waveguide. (a)–(d) Flexural wave propagation through the structural wave cloak at time instants of t = 0.04 ms, t = 0.07 ms, t = 0.09 ms and t = 0.25 ms. (e)–(j) Flexural wave propagation through the structural waveguide at time instants of t = 0.03 ms, t = 0.08 ms, t = 0.13 ms, t = 0.18 ms, t = 0.23 ms, and t = 0.25 ms.
