When metal nanoparticles are arranged in an ordered array, they may scatter light to
produce diffracted waves. If one of the diffracted waves then propagates in the plane of the …

Engineering nanostructures with exceptionally high-Q resonances mediated by the Fano-
type hybridization between discrete states associated with the periodicity of the structure and …

Recently, we witnessed a tremendous effort to conquer the realm of acoustics as a possible
playground to test with topologically protected sound wave propagation. In this article, we …

Despite the extraordinary degree of interest in optical metamaterials in recent years, the
hoped-for devices and applications have, in large part, yet to emerge. It is becoming clear …

Photonic metasurfaces, that is, two-dimensional arrangements of designed plasmonic or
dielectric resonant scatterers, have been established as a successful concept for controlling …

This Feature Article describes research on the optical properties of arrays of silver and gold
nanoparticles, particles that exhibit localized surface plasmon resonances in the visible and …

Valleytronics is quickly emerging as an exciting field in fundamental and applied research.
In this Letter, we study the acoustic version of valley states in sonic crystals and reveal a …

Artificial honeycomb lattices offer a tunable platform for studying massless Dirac
quasiparticles and their topological and correlated phases. Here we review recent progress …

Pursuing topological phases in natural and artificial materials is one of the central topics in
modern physical science and engineering. In classical magnetic systems, spin waves (or …
