To mitigate surface waves in ambient vibration, a novel broadband elastic metasurface is
proposed by periodically burying the layered in-filled pipes below the ground surface. The …

Metamaterials are composed of arrays of subwavelength-sized artificial structures; these
architectures give rise to novel characteristics that can be exploited to manipulate …

Metasurfaces of mechanical resonators have been successfully used to control in-plane
polarized surface waves for filtering, waveguiding and lensing applications across different …

We show efficient elastic energy transfer and wave confinement through a graded array of
resonators attached to an elastic beam. Experiments demonstrate that flexural resonators of …

In this paper, a new type of low-frequency broadband elastic metamaterial is proposed,
which is constituted of periodic I-shaped pillars arranged on a two-dimensional ground …

We inspect the propagation of shear polarized surface waves akin to Love waves through a
forest of trees of the same height atop a guiding layer on a soil substrate. An asymptotic …

We combine two different fields, topological physics and graded metamaterials, to design a
topological metasurface to control and redirect elastic waves. We strategically design a two …

In this work, we propose an inertial amplified resonator (IAR) as a building block of a tunable
locally resonant metasurface. The IAR consists in a mass–spring resonator coupled with two …

There has been a rising interest in utilizing metamaterials to manipulate the propagation of
surface waves, including Rayleigh waves. These novel materials have a diverse range of …

An innovative special class of tunable periodic metamaterials is designed, suitable for
realizing high-performance acoustic filters. The metamaterial is made up of a phononic …
