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 …

This broad review summarizes recent advances and “hot” research topics in nanophononics
and elastic, acoustic, and mechanical metamaterials based on results presented by the …

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 …

Active mechanical metamaterials (AMMs)(or smart mechanical metamaterials) that combine
the configurations of mechanical metamaterials and the active control of stimuli‐responsive …

Various kinds of optical devices have been designed for unique functionality based on a
deeper understanding of optical principles. Recently, the research of functional optics has …

After a decade of periodic truss-, plate-, and shell-based architectures having dominated the
design of metamaterials, we introduce the non-periodic class of spinodoid topologies …

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

Mechanical metamaterials, also known as architected materials, are rationally designed
composites, aiming at elastic behaviors and effective mechanical properties beyond ('meta') …

In the past two decades, the research on acoustic metamaterials has flourished, which is
also benefited from the development of additive manufacturing technology. The exotic …

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 …
