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 …

Architected materials that control elastic wave propagation are essential in vibration
mitigation and sound attenuation. Phononic crystals and acoustic metamaterials use band …

The small mass and high coherence of nanomechanical resonators render them the ultimate
mechanical probe, with applications that range from protein mass spectrometry and …

In this study, the periodic nested acoustic black hole phononic structure is presented, and
different complex band structures and corresponding evanescent Bloch wave propagation …

We investigate theoretically the band structure of flexural waves propagating in an elastic
metamaterial thin plate. Kirchhoff-Love thin plate theory is considered. We study the …

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

Propagation of elastic waves in acoustic metamaterials based on locally resonant
viscoelastic phononic crystals is discussed. A variational formulation of the complex band …

We investigate the complex band structure and forced response of flexural waves
propagating in an elastic metamaterial thick plate. Mindlin-Reissner thick plate theory is …

The objective of this paper is to present a peer-review of the literature and trends
surrounding the design of phononic crystals (PnCs) using topology optimization methods …
