Guided waves, elastic waves propagating through bounded structures, play a pivotal role in
various applications, including ultrasonic non-destructive testing and structural health …

Metamaterials (MMs), which include phononic crystals (PCs) as a particular type, exhibit
anomalous wave propagation properties through artificial design of topologies or lattice …

This paper proposes the design of an active nonlinear metamaterial for broadband and
tunable low-frequency wave attenuation governed by a lever-based nonlinear amplification …

We propose a design of a metamaterial for magnetically tunable propagation of nonlinear
vector solitary waves. The metamaterial consists of a periodic array of units of hard-magnetic …

Metamaterials are engineered materials with unusual, unique properties and advanced
functionalities that are a direct consequence of their microarchitecture. While initial …

Transverse spin of surface waves is a universal phenomenon which has recently attracted
significant attention in optics and acoustics. It appears in gravity water waves, surface …

This investigation proposes a novel elastic metasurface tailored to convert a longitudinal
wave into a transverse wave and vice versa at an arbitrary refraction angle with full (100%) …

An original parametric lattice model is proposed to investigate harmonic and superharmonic
planar waves propagating in a two-dimensional mechanical metamaterial, whose periodic …

The interaction between waves and evolving media challenges traditional conservation
laws. We experimentally investigate the behavior of elastic wave packets crossing a moving …

We propose a metamaterial design principle that enables the remote switching of
topological states. Dynamic breaking of space-inversion symmetry is achieved through the …
