Phononic crystals (PnCs) control the transport of sound and heat similar to the control of
electric currents by semiconductors and metals or light by photonic crystals. Basic and …

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 …

Metamaterial systems have opened new, unexpected, and exciting paths for the design of
acoustic devices that only few years ago were considered completely out of reach. However …

The central concept in phononics is the tuning of the phonon dispersion relation, or phonon
engineering, which provides a means of controlling related properties such as group velocity …

In engineering acoustics, the propagation of elastic flexural waves in plate and shell
structures is a common transmission path of vibrations and structure-borne noises. Phononic …

This paper studies periodically arranged seismic barriers consisting of finite and infinite
lattices to mitigate seismic surface waves in layered soils. Using Bloch-Flouquet theory …

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 …

Controlling the propagation of seismic waves to protect critical infrastructure via
metamaterial is of new topical interest. This approach can be implemented by remote …

This paper presents experimental evidence for the existence of acoustic valley Hall edge
(AVHE) states in topological elastic waveguides. The fundamental lattice is assembled on …

Two dimensional phononic metamaterials, consisting of plates with resonant cylinders have
been shown to attenuate waves much larger than their characteristic unit cell size by …
