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 …

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 …

Photoelectron transfer between heterojuctions is an important process for photocatalysis,
and identification of the electron transfer process provides valuable information for catalyst …

As a new kind of artificial material developed in recent decades, metamaterials exhibit novel
performance and the promising application potentials in the field of practical engineering …

We introduce here the concept of acoustic parity-time (PT) symmetry and demonstrate the
extraordinary scattering characteristics of the acoustic PT medium. On the basis of exact …

The advancement in electromagnetic metamaterials, which commenced three decades ago,
experienced a rapid transformation into acoustic and elastic systems in the forms of …

Metamaterials and phononic crystals (PCs) with artificially designed periodic microstructures
have attracted increasing research interests due to their unique properties that cannot be …

Phononic crystal is a type of artificial heterogeneous material constituted by a periodic
repetition of cells. This characteristic provides a possible solution to the accurate …

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 …

In this paper, we present a theoretical model for the analysis of large magneto-deformation
and the anti-plane shear wave bandgaps in 2D periodic two-phase hard magnetic soft …
