Flexible manipulation of elastic and acoustic waves through phononic meta-structured
materials (PMSMs) has attracted a lot of attention in the last three decades and shows a …

Engineering applications concurrently face challenges related to vibration, impact, load-
bearing and energy absorption. Here, an arch-honeycomb metamaterial with split-ring …

We report a new method to tailor the entire two-dimensional (2D) dispersion relation based
on nonlocal phononic crystals, where beyond-nearest-neighbor (BNN) interactions are used …

Band structure and Dirac degeneracy are essential features of sonic crystals/acoustic
metamaterials to achieve advanced control of exciting wave effects. In this work, we explore …

This study introduces the concept of nonlocal effect into a monoatomic mass–spring periodic
structure, leading to unique characteristics of dispersion curves. Through the incorporation …

Z-classified topological phases lead to a larger-than-unity number of topological states.
However, these multiple topological states are only localized at the corners in nonlocal …

Some popular mechanisms for restricting the diffusion of waves include introducing disorder
(to provoke Anderson localization) and engineering topologically non-trivial phases (to allow …

Ohm's law of electric conduction is local in the sense that the current density at one position
only depends on the electric field at that same position. For a nonlocal medium, the current …

Beams are fundamental objects in solid mechanics, displaying flexural and torsional modes
in three dimensions, and support important applications across all fields of engineering …

Evanescent Bloch waves are eigensolutions of spatially periodic problems for complex-
valued wavenumbers at finite frequencies, corresponding to solutions that oscillate in time …
