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 …

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 present a review, through selected illustrative examples, of the physics of classical
vibrational modes in phononic lattices, which elaborates on the theory, the formalism, the …

We investigate the propagation of elastic waves in four periodic porous elastomeric planar
structures, where pattern transformation is induced by mechanical instability under uniaxial …

In this paper, we present theoretical formalisms for the study of wave dispersion in damped
elastic periodic materials. We adopt the well known structural dynamics techniques of modal …

The development of seismic metamaterials has attracted much research interest in the past
decade. Efforts have been made by using experimental and theoretical approaches to …

Thin rubber layers with air-filled cavities can be used as anechoic submarine coatings.
Normally incident sonar energy is redistributed in the lateral direction and absorbed. In this …

The influence of material loss on the complex band structure of two-dimensional phononic
crystals is investigated. A viscoelasticity model is added to the extended plane-wave …

We present a theory for Bloch wave propagation in damped elastic media. We expand the
eigenvalue problem governing the dispersion relation using a set of Bloch mode …
