The Acoustics in Complex Media Group at UPV’s Gandia Campus has developed a versatile portfolio of acoustic metamaterials. Subwavelength designs, including Helmholtz-resonator arrays, toroidal scatterers, space-coiled units, and folded-textile structures, have been used to achieve tailored band gaps, directional waveguiding, GRIN-type focusing, and broadband diffusion. Sonic-crystal sound diffusers and resonator-loaded panels have been implemented to enhance sound scattering and reflection control. Metamaterial panels for rocket-launch noise mitigation were fabricated under European Spatial Agency (ESA) funding, with prototypes demonstrating perfect absorption at high sound pressures. Acoustic black holes have been embedded in plates by introducing periodic power-law tapers to trap flexural waves and damp vibrations, thereby creating passive vibration sinks on structural surfaces. Research has recently been focused on spatiotemporal metamaterials, particularly moving-interface slabs and time-varying Helmholtz-resonator waveguides, where forward/backward wave splitting, frequency conversion, and non-reciprocity have been observed.
