“…Gold nanorods provide a good model system for developing this understanding, because they have been studied theoretically in detail [165][166][167][168][169][170][171][172][173][174][175][176][177][178], and because their relatively simple Figure 15 (online color at: www.lprjournal.org) Top: schematic and dimensions of a cylindrical nanorod with hemispherical ends. Bottom: surface charge density along the edge of the rod for a dipole resonance.…”

The rapid emergence of nanoplasmonics as a novel technology has been driven by recent progress in the fabrication, characterization, and understanding of metal-nanoparticle systems. In this review, we highlight some of the key advances in each of these areas. We emphasize the basic physical understanding and experimental techniques that will enable a new generation of applications in nano-optics.

“…Such techniques hold promise of potential applications in imaging, surface-enhanced Raman spectroscopy (SERS), lithography, optoelectronic devices, and biosensing. In recent years, the increasing research effort in the field of plasmonics-the study of EM field confinement and enhancement via surface plasmons (SPs)-has prompted advances in the theoretical studies of light scattering from nanostructures [8][9][10][11][12][13][14][15][16][17]. One of the most important applications of localized plasmons in nanoparticles is SERS [9,[18][19][20]; a very high sensitivity has been achieved with this spectroscopic technique, making possible, in fact, single-molecule detection [21,22].…”

We study theoretically the light scattering from metal wires of arbitrary cross section, with emphasis on the occurrence of plasmon resonances. We make use of the rigorous formulation of the Green's theorem surface integral equations of the electromagnetic wave scattering, written for an arbitrary number of scatterers described in parametric form. We have investigated the scattering cross sections for nanowires of various shapes (circle, triangles, rectangles, and stars), either isolated or interacting. The relationship between the cross sectional shape and the spectral dependence of the plasmon resonances is studied, including the impact of nanoparticle coupling in the case of interacting scatterers. Near-field intensity maps are also shown that shed light on the plasmon resonance features and the occurrence of local field enhancements.

“…Surface plasma waves (surface plasmons), when one of the media is plasma, attracted special interests for many applications, for example, in plasmonics [26], in light sources as spasers [27], and in nanoantennas [28]. The surface wave fields include information on the properties of adjacent media and therefore can affect electromagnetic waves in one of them by properties of another one [29].…”

The electromagnetic wave propagation in a complex plasma containing macroparticle inclusions (dust) is reviewed. We focus on two classes of phenomena due to the presence of dust:(1), collection of plasma electrons and ions by macroparticle inclusions and related modification of dielectric properties, and (2), surface plasmon resonances on the macroparticle surfaces and their effect on electromagnetic wave propagation. It is demonstrated that the presence of these phenomena can significantly modify plasma electromagnetic properties by introducing additional (charging) damping, modifying field distributions near macroparticles, and leading to resonances and cut-offs in the effective permittivity. The conditions to observe such phenomena in laboratory dusty plasma and/or space (cosmic) dusty plasmas are discussed. ARTICLE HISTORY
