This paper reviews recent progress in acoustic metasurfaces and the novel concept of"
topological acoustic/phononics" for designing compact yet efficient acoustic devices. After a …

Phononic crystal (PnC) has attracted strong attention due to its tremendous capabilities to
manipulate acoustic and elastodynamic waves. For high frequency (gigahertz) PnC, the size …

Phononic crystals (PnCs) with a broad bandgap have been the subject of extensive
research, particularly for their capacity to manipulate elastic waves efficiently. However, the …

Transverse thermoelectric performance of the artificially tilted multilayer thermoelectric
device (ATMTD) is very difficult to be optimized, due to the large degree freedom in device …

Based on the concept of band topology in phonon dispersion, we designed a topological
phononic crystal in a thin plate for developing an efficient elastic waveguide. Despite that …

Combining metallic and ceramic properties, and as precursors for MXenes, MAX phases
have attracted extensive attention. In recent years, A-element substitution has been …

Coherent thermal transport has recently become a subject of considerable interest, but
whether some intriguing phenomena of phonon coherence (including Brillouin zone folding …

This paper introduces and models a phononic structure based on single-crystal silicon,
aiming to investigate the width of its frequency bandgap and the impact of key parameters …

The size-dependent band structure of an Si phononic crystal (PnC) slab with an air hole is
studied by utilizing the non-classic wave equations of the nonlocal strain gradient theory …

In this paper, a novel coupling technique is developed in continuum–atomistic multi-scale
analysis of temperature field problems. In this manner, a new thermostat is introduced based …
