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

From the beginning of the 20th century, researchers have been interested in surface
electromagnetic waves guided by planar interfaces of dissimilar mediums. Much initial …

A double-periodic array of pairs of parallel gold nanorods is shown to have a negative
refractive index in the optical range. Such behavior results from the plasmon resonance 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 …

For decades, the surface-plasmon-polariton wave guided by the interface of simple isotropic
materials dominated the scene. However, in recent times research on electromagnetic …

Decades ago, Veselago predicted that a material with simultaneously negative electric and
magnetic polarization responses would yield a 'left-handed'medium in which light …

The action of complex arrangements of matter on electromagnetic waves lies at the heart of
this book. Herein, we generally regard matter from a macroscopic perspective, which means …

From the fundamental requirement of causality, we derive a rigorous criterion of negative
refraction (left handedness). This criterion imposes the lower limits on the electric and …

We experimentally demonstrate a low-loss multilayered metamaterial exhibiting a double-
negative refractive index in the visible spectral range. To this end, we exploit a second-order …

A theory is presented of the negative refractive index observed in the so-called double-
fishnet structures. We find that the electrical response of these structures is dominated by the …
