In solid state physics, a bandgap (BG) refers to a range of energies where no electronic
states can exist. This concept was extended to classical waves, spawning the entire fields of …

The study of phononic materials and structures is an emerging discipline that lies at the
crossroads of vibration and acoustics engineering and condensed matter physics. Broadly …

Seismic metamaterial (SM) has lately received significant attention in the field of vibration
isolation and damping due to its wave manipulation and bandgap properties. However, the …

We report a new class of tunable and switchable acoustic metamaterials comprising
resonating units dispersed into an elastic matrix. Each resonator consists of a metallic core …

Linear acoustic metamaterials (LAMs) are widely used to manipulate sound; however, it is
challenging to obtain bandgaps with a generalized width (ratio of the bandgap width to its …

Locally resonant metamaterials are characterized by bandgaps at wavelengths that are
much larger than the lattice size, enabling low-frequency vibration attenuation. Typically …

The authors study the propagation of flexural waves in a locally resonant (LR) thin plate
made of a two-dimensional periodic array of spring–mass resonators attached on a thin …

This paper is concerned with flexural wave propagation and vibration transmission in beams
with periodically attached vibration absorbers. Such periodic systems feature unique wave …

Phononic crystals are composite materials made of periodic distributions of inclusions
embedded in a matrix. Due to their periodic structure, these materials may exhibit under …

The book provides a comprehensive presentation of the topic of phononic and sonic
crystals, including acoustic and elastic wave propagation in homogeneous and periodic …
