In electromagnetics and photonics,'nonlocality'refers to the phenomenon by which the
response/output of a material or system at a certain point in space depends on the input field …

Metamaterials are artificial materials designed to exhibit effective material parameters that
go beyond those found in nature. Composed of unit cells with rich designability that are …

The introduction of engineered resonance phenomena on surfaces has opened a new
frontier in surface science and technology. Pillared phononic crystals, metamaterials, and …

Causality of linear time-invariant systems inherently defines the wave-matter interaction
process in wave physics. This principle imposes strict constraints on the interfacial response …

Metasurfaces are arrays of subwavelength spaced nanostructures that can manipulate the
amplitude, phase, and polarization of light to achieve a variety of optical functions beyond …

Elastic metasurfaces have become one of the most promising platforms for manipulating
mechanical wavefronts with the striking feature of ultra-thin geometry. The conventional …

Extreme impedance mismatch causes sound insulation at water–air interfaces, limiting
numerous cross‐media applications such as ocean‐air wireless acoustic communication …

Solids built out of active components have exhibited odd elastic stiffness tensors whose
active moduli appear in the antisymmetric part and which give rise to non-Hermitian static …

This paper introduces the concept of nonlocal Acoustic Black Hole (ABH) metastructure and
explores, via numerical analyzes, the corresponding vibration attenuation performance …

Guided waves, elastic waves propagating through bounded structures, play a pivotal role in
various applications, including ultrasonic non-destructive testing and structural health …
