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

Metasurface has great capabilities in tailoring the electromagnetic (EM) waves in a
controllable way owing to the carefully designed and arranged subwavelength meta-atoms …

In this Letter, we demonstrate highly efficient, polarization-insensitive planar lenses
(metalenses) at red, green, and blue wavelengths (λ= 660, 532, and 405 nm). Metalenses …

Metasurfaces are two-dimensional structures enabling complete control on light amplitude,
phase, and polarization. Unlike plasmonic metasurfaces, silicon structures facilitate high …

Recently, metasurfaces have received increasing attention due to their ability to locally
manipulate the amplitude, phase and polarization of light with high spatial resolution …

We experimentally demonstrate a functional silicon metadevice at telecom wavelengths that
can efficiently control the wavefront of optical beams by imprinting a spatially varying …

Over the past 5 years, digital coding and programmable metamaterials have been
developed rapidly since their first exhibition in 2014. The iconic feature of the digital coding …

Over the past decade, static metasurfaces have proved to be low-profile and efficient
apparatuses for transformation of electromagnetic waves. However, such metasurfaces are …

As optical metasurfaces become progressively ubiquitous, the expectations from them are
becoming increasingly complex. The limited number of structural parameters in the …

This review overviews the state of the art of research into high-index dielectric
nanoresonators and their use in functional photonic nanostructures at optical frequencies …
