The growing maturity of nanofabrication has ushered massive sophisticated optical
structures available on a photonic chip. The integration of subwavelength-structured …

Metamaterials are composed of periodic subwavelength metal/dielectric structures that
resonantly couple to the electric and/or magnetic components of the incident …

Conventional optical components such as lenses, waveplates and holograms rely on light
propagation over distances much larger than the wavelength to shape wavefronts. In this …

Surfaces covered by ultrathin plasmonic structures—so-called metasurfaces,,,—have
recently been shown to be capable of completely controlling the phase of light, representing …

Metamaterials are artificial structures that are usually described by effective medium
parameters on the macroscopic scale, and these metamaterials are referred to as 'analog …

Polaritons are hybrid excitations of matter and photons. In recent years, polaritons in van der
Waals nanomaterials—known as van der Waals polaritons—have shown great promise to …

Colloidal self-assembly refers to a solution-processed assembly of nanometer-/micrometer-
sized, well-dispersed particles into secondary structures, whose collective properties are …

The mechanical properties of ordinary materials degrade substantially with reduced density
because their structural elements bend under applied load. We report a class of …

Metasurfaces are 2D artificial materials consisting of arrays of metamolecules, which are
exquisitely designed to manipulate light in terms of amplitude, phase, and polarization state …

We review the basic physics and applications of a special class of planar metamaterials,
often called metasurfaces, which are composed of optically thin and densely packed planar …
