In this work, we investigate the dynamics and attenuation properties of a one-dimensional inertial amplified lattice with opposite chirality. The unit cell of the structure consists of a hollow-square plate connected to a ring through arch-like ligam

In this work, we experimentally and numerically investigate the propagation and attenuation of vertically polarized surface waves in an unconsolidated granular medium equipped with small-scale metabarriers of different depths, i.e., arrays composed o

In this article the physics of horizontally polarized shear waves travelling across a locally resonant metasurface in an unconsolidated granular medium is experimentally and numerically explored. The metasurface is comprised of an arrangement of sub-

The article analyses two potential metamaterial designs, the metafoundation and the metabarrier, capable to attenuate seismic waves on buildings or structural components in a frequency band between 3.5 to 8 Hz. The metafoundation serves the dual purp

Elastic metasurfaces composed of arrays of subwavelength mechanical oscillators located at the free surface of an elastic medium have been proposed to manipulate the propagation of surface waves at diverse length scales. In particular, metasurfaces o

Arrays of mechanical resonators, referred to as metasurfaces, have proven capable of controlling in-plane polarized surface waves across multiple length scales, i.e., from the micrometer scale, for the design of devices for sensing applications, up t
