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 …

The strong optical chirality arising from certain synthetic metamaterials has important and
widespread applications in polarization optics, stereochemistry and spintronics. However …

Metasurfaces as optically thin composite layers can be modeled as electric and magnetic
surface current sheets flowing in the layer volume in the metasurface plane. In the most …

Three-dimensional chiral plasmonic metasurfaces were demonstrated to offer enormous
potential for ultrathin circular polarizers and applications in chiral sensing. However, the …

Chirality describes mirror symmetry breaking in geometric structures or certain physical
quantities. The interaction between chiral structure and chiral light provides a rich collection …

Over the years, researchers have been exploring ways to artificially design chiral structures
and materials, namely metamaterials and metasurfaces. They exhibit unique optical …

Chiral plasmonics is a fascinating research field that is attractive to scientists from diverse
backgrounds. Physicists study light–matter interactions, chemists seek ways to analyze …

Chiral materials, which show different optical behaviors when illuminated by left or right
circularly polarized light due to broken mirror symmetry, have greatly impacted the field of …

We study experimentally second-harmonic generation from arrays of split-ring resonators at
oblique incidence and find conditions of more than 30-fold enhancement of the emitted …
