Metasurfaces are ultrathin metamaterials consisting of planar electromagnetic (EM)
microstructures (eg, meta-atoms) with pre-determined EM responses arranged in specific …

Compared with conventional optical elements, 2D photonic metasurfaces, consisting of
arrays of antennas with subwavelength thickness (the 'meta-atoms'), enable the …

On-chip photonic systems play crucial roles in nanoscience and nanoapplications, but
coupling external light to these subwavelength devices is challenging due to a large mode …

Metasurfaces are planar metamaterials exhibiting certain inhomogeneous phase
distributions for transmitted or reflected waves, which can efficiently reshape the wave‐fronts …

Space-time wave packets (STWPs) constitute a broad class of pulsed optical fields that are
rigidly transported in linear media without diffraction or dispersion, and are therefore …

Surface plasmons (SPs) are electromagnetic surface waves that propagate at the interface
between a conductor and a dielectric. Due to their unique ability to concentrate light on two …

Metasurfaces with subwavelength thicknesses have exhibited unconventional phenomena
in ways that could not be mimicked by traditional materials. Here we report on the analytical …
