The concept of metamaterials originates from the proposal of left-hand materials with
negative refractive index, followed by which, varieties of metamaterials with kinds of fantastic …

Vibration and sound control is critical to many practical engineering systems in order to
minimise the detrimental effects caused by unavoidable vibrations and noises …

Phononic crystals (PCs) and metamaterials (MMs) can exhibit abnormal properties, even far
beyond those found in nature, through artificial design of the topology or ordered structure of …

Acoustic metasurfaces derive their characteristics from the interaction between acoustic
waves and specifically designed materials. The field is driven by the desire to control …

Inspired by sonic engineering, locally resonant metamaterials have attracted much attention
from researchers in civil engineering for their unique characteristics of stress wave …

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 …

Acoustic metamaterials can manipulate and control sound waves in ways that are not
possible in conventional materials. Metamaterials with zero, or even negative, refractive …

Within a time span of 15 years, acoustic metamaterials have emerged from academic
curiosity to become an active field driven by scientific discoveries and diverse application …

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 …
