Acoustic metamaterials have subwavelength characteristics and hence they can be used for
the low-frequency noise and vibration control. Usually, acoustic metamaterials have …

In this work, we propose the use of contact resonances, controlled via an external magnetic
field, as a tunable platform to manipulate the dispersion of surface acoustic waves (SAWs) …

Zero group velocity (ZGV) modes can be utilized in many applications in both optics and
acoustics. There exist numerous realizations of metamaterials with ZGVs at higher …

We study a magnetogranular chain composed of stainless-steel beads which are placed
inside an appropriately designed periodic magnetic field. The latter provides attractive forces …

Additive Manufacturing (AM) is widely used to fabricate phononic crystals (PnCs) in recent
years. Friction Stir Additive Manufacturing (FSAM) is a new-type solid state fabrication …

The Bragg gap that stops wave propagation may not be formed from zero or a very low
frequency unless the periodicity of a periodic system is unrealistically large. Accordingly, the …

In this work we present an analytical and numerical study of rogue and solitary waves in a
coupled one-dimensional nonlinear lattice that involves both axial and rotational degrees of …

Metamaterial with various degrees of bandgap tunability is an emerging area in
manipulating elastic wave transmission characteristics for next generation phononic …

Longitudinal contact-based vibrations of colloidal crystals with a controlled layer thickness
are studied. These crystals consist of 390 nm diameter polystyrene spheres arranged into …

We study the dynamics of an ordered hexagonal monolayer of polystyrene microspheres
adhered to a glass substrate coated with a thin aluminum layer. A laser-induced transient …
