Phononic crystals (PnCs) are capable of manipulating the flow of elastic energy through
their periodic structures and have emerged as a promising field in the last two decades …

Understanding contact mechanics and adhesion processes in thin films and micro-
structured materials is fundamental in phonon and heat transport phenomena and is …

We investigate the propagation of Rayleigh waves in a half-space coupled to a nonlinear
metasurface. The metasurface consists of an array of nonlinear oscillators attached to the …

The hypersonic phonon propagation in large-area two-dimensional colloidal crystals is
probed by spontaneous micro Brillouin light scattering. The dispersion relation of thermally …

Contact-based vibrations play an essential role in the dynamics of granular materials.
Significant insights into vibrational granular dynamics have previously been obtained with …

We extend time-domain imaging in acoustic metamaterials to gigahertz frequencies. Using a
sample consisting of a regular array of∼ 1 μm diameter silica microspheres forming a two …

The vibrational properties of a face-centered cubic granular crystal of monodisperse
particles are predicted using a discrete model as well as two micropolar models, first the …

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) …

The aim of this Letter is to introduce a new optical tweezers approach, called scanning
holographic optical tweezers (SHOT), which drastically increases the working area (WA) of …

We present a method for the recovery of complex wavenumber information via spatial
Laplace transforms of spatiotemporal wave propagation measurements. The method aids in …
