Flat optics has emerged as a key player in the area of structured light and its applications,
owing to its subwavelength resolution, ease of integration, and compact footprint. Although …

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

The recently proposed digital coding metasurfaces make it possible to control
electromagnetic (EM) waves in real time, and allow the implementation of many different …

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 …

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 …

Currently, the development of circularly polarized luminescent (CPL) materials has drawn
extensive attention due to the numerous potential applications in optical data storage …

Background Metamaterials (MMs) are smartly engineered structures with rationally
designed, nanostructured building blocks that allow us to build devices with distinct …

Plasmonic gold nanoparticles have been used increasingly in solid-state systems because
of their applicability in fabricating novel sensors, heterogeneous catalysts, metamaterials …

Light detection and ranging (LiDAR) sensors enable precision sensing of an object in 3D.
LiDAR technology is widely used in metrology, environment monitoring, archaeology, and …

Huygens' principle is a well-known concept in electromagnetics that dates back to 1690.
Here, it is applied to develop designer surfaces that provide extreme control of …
