Phononic crystals (PCs) and metamaterials (MMs) can exhibit abnormal properties, even far
beyond those found in nature, through artificial design of the topology or ordered structure of …

Phononic materials are periodically arranged building blocks in the form of material
properties, geometries, and/or boundary conditions. This synthetic architecture makes …

The study of granular crystals, which are nonlinear metamaterials that consist of closely
packed arrays of particles that interact elastically, is a vibrant area of research that combines …

A nonlinear chain with sixth-order polynomial on-site potential is used to analyze the
evolution of the total-to-kinetic-energy ratio during development of modulational instability of …

Bragg scattering in periodic media generates bandgaps, frequency bands where waves
attenuate rather than propagate. Yet, a finite periodic structure may exhibit resonance …

We investigate the tunable vibration filtering properties of statically compressed one-
dimensional diatomic granular crystals composed of arrays of stainless steel spheres and …

The effect of discrete breathers (DBs) on macroscopic properties of the Fermi-Pasta-Ulam
chain with symmetric and asymmetric potentials is investigated. The total to kinetic energy …

The propagation of acoustic and elastic waves in time-varying, spatially homogeneous
media can exhibit different phenomena when compared to traditional spatially varying …

We study the formation of frequency band gaps in single column woodpile phononic crystals
composed of orthogonally stacked slender cylinders. We focus on investigating the effect of …
