Realization of a small-scale thick resonant wave barrier for surface Rayleigh waves and its experimental testing

The study involves designing and testing a thick resonant wave barrier to suppress surface Rayleigh wave propagation. This barrier consists of a grid of embedded resonators in the host material (here a PVC plate). To conduct experiments, a scaled-down prototype is employed by perforating the PVC plate and press-fitting the resonators. Surface waves are generated using Piezoelectric transducers glued to the metamaterial plate. A Scanning Laser Doppler Vibrometer (SLDV) records the plate's response, facilitating the reconstruction of the experimental surface wave dispersion relation within the thick resonant layer through post-processing techniques.
