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 …

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 …

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 black hole (ABH) structures have been widely utilized for vibration suppression
owing to its tailored indentations according to a power-law profile. Compared with single …

Skyrmions with topologically stable configuration have shown a promising route toward high-
density magnetic and photonic information processing due to their defect-immune and low …

This paper presents a comprehensive review of the literature and trends on the design of
periodic microstructural composite materials including photonic crystals (PtCs), phononic …

Elastic metamaterials with local resonance bandgaps are promising for low-frequency
vibration mitigation. However, such locally resonant metamaterials inherently possess …

Emerging interest to synthesize active, engineered matter suggests a future where smart
material systems and structures operate autonomously around people, serving diverse roles …

Due to their limited number of units but outstanding ability to control rather complex wave-
propagation phenomena, acoustic coding metasurfaces (ACMs) as two-dimensional …

Pentamode metamaterials (PMs), a kind of metafluids composed of complex solid medium,
have shown enormous potential for both elastic wave and underwater acoustic wave …
