In electromagnetics and photonics,'nonlocality'refers to the phenomenon by which the
response/output of a material or system at a certain point in space depends on the input field …

Metamaterials, artificial electromagnetic media that are structured on the subwavelength
scale, were initially suggested for the negative-index'superlens'. Later metamaterials …

Linear acoustic metamaterials (LAMs) are widely used to manipulate sound; however, it is
challenging to obtain bandgaps with a generalized width (ratio of the bandgap width to its …

Metamaterials, artificial composite structures with exotic material properties, have emerged
as a new frontier of science involving physics, material science, engineering and chemistry …

This Colloquium presents an overview of the research on nonlinear electromagnetic
metamaterials. The developed theoretical approaches and experimental designs are …

Underpinned by the advent of metamaterials, transformation optics offers great versatility for
controlling electromagnetic waves to create materials with specially designed properties …

Artificially engineered metamaterials are now demonstrating unprecedented
electromagnetic properties that cannot be obtained with naturally occurring materials. In …

In the past few years, new developments in structured electromagnetic materials have given
rise to negative refractive index materials which have both negative dielectric permittivity …

We derive from first principles an accurate homogenized description of periodic
metamaterials made of magnetodielectric inclusions, highlighting and overcoming relevant …

Periodic nanostructures in photonics facilitate a far-reaching control of light propagation and
