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 …

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

This article reviews recent progress leading to the realization of planar optical components
made of a single layer of phase shifting nanostructures. After introducing the principles of …

BACKGROUND Future high-performance portable and wearable optical devices and
systems with small footprints and low weights will require components with small form …

Holography, a revolutionary 3D imaging technique, has been developed for storing and
recovering the amplitude and phase of light scattered by objects. Later, single-beam …

The concept of optical phase discontinuities is applied to the design and demonstration of
aberration-free planar lenses and axicons, comprising a phased array of ultrathin …

The replacement of bulk refractive optical elements with diffractive planar components
enables the miniaturization of optical systems. However, diffractive optics suffers from large …

In this brief review, we summarize and elaborate on some of the nomenclature of polaritonic
phenomena and systems as they appear in the literature on quantum materials and …

We combine theory and experiment to demonstrate that a carefully designed gradient meta-
surface supports high-efficiency anomalous reflections for near-infrared light following the …
