Mechanical metamaterials enable the creation of structural materials with unprecedented
mechanical properties. However, thus far, research on mechanical metamaterials has …

Mechanical metamaterials are engineered materials with unconventional mechanical
behavior that originates from artificially programmed microstructures along with intrinsic …

A review is given on the foundations and applications of non-Hermitian classical and
quantum physics. First, key theorems and central concepts in non-Hermitian linear algebra …

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

Embedding mechanical logic into soft robotics, microelectromechanical systems (MEMS),
and robotic materials can greatly improve their functional capacity. However, such logical …

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 …

The use of mechanical forces to chemically transform polymers dates back decades. In
recent years, the use of mechanochemistry to direct constructive transformations in polymers …

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

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