Surface plasmon polaritons (SPPs) are electromagnetic excitations existing at the interface
between a metal and a dielectric material. Remarkable progress has been made in the field …

Nanoparticles of noble metals belong to the most extensively studied colloidal systems in
the field of nanoscience and nanotechnology. Due to continuing progress in the synthesis of …

Surface plasmons are waves that propagate along the surface of a conductor. By altering the
structure of a metal's surface, the properties of surface plasmons—in particular their …

Metals such as silver support surface plasmons: electromagnetic surface excitations
localized near the surface that originate from the free electrons of the metal. Surface modes …

Nanowires supporting propagating surface plasmons can function as nanowaveguides to
realize the light guiding with field confinement beyond the diffraction limit, providing …

Long-range surface plasmon polaritons (LRSPPs) are optical surface waves that propagate
along a thin symmetric metal slab or stripe over an appreciable length (centimeters) …

Metallic particles and surfaces display diverse and complex optical properties. Examples
include the intense colors of noble metal colloids, surface plasmon resonance absorption by …

We report on chemically prepared silver nanowires (diameters around 100 nm) sustaining
surface plasmon modes with wavelengths shortened to about half the value of the exciting …

We probe the influence of grating effects on plasmon excitations in gold nanoparticles
arranged in regular two-dimensional patterns. Samples produced by electron-beam …

Plasmonic waveguides can guide light along metal–dielectric interfaces with propagating
wave vectors of greater magnitude than are available in free space and hence with …
