Metamaterials are rationally designed composites aiming at effective material parameters
that go beyond those of the ingredient materials. For example, negative metamaterial …

BACKGROUND Nanoscale optics is usually associated with plasmonic structures made of
metals such as gold or silver. However, plasmonics suffers from high losses of metals …

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

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 …

The prospect of creating metamaterials with optical properties greatly exceeding the
parameter space accessible with natural materials has been inspiring intense research …

The ideal material for nanophotonic applications will have a large refractive index at optical
frequencies, respond to both the electric and magnetic fields of light, support large optical …

In this Letter, we experimentally report an achromatic metalens (AML) operating over a
continuous bandwidth in the visible. This is accomplished via dispersion engineering of …

In the wake of intense research on metamaterials the two-dimensional analogue, known as
metasurfaces, has attracted progressively increasing attention in recent years due to the …

The original Kerker effect was introduced for a hypothetical magnetic sphere, and initially it
did not attract much attention due to a lack of magnetic materials required. Rejuvenated by …

Nonlinear optical phenomena in nanostructured materials have been challenging our
perceptions of nonlinear optical processes that have been explored since the invention of …
