“…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].…”

“…When we are interested in interacting particles of arbitrary shape, numerical calculations are required. Different formulations exist that rigorously describe the response of metallic nanoparticles of arbitrary shape: finite-difference time domain [24], dyadic Green's function technique [9,25], and various implementations of the boundary integral methods [8,[26][27][28] based on Green's second theorem (when the dielectric function is constant within the nanoparticle volume) are the most widely employed.…”

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.

“…s and p waves can be defined as usual, with the electric field perpendicular or parallel to the plane of incidence, respectively. To compute the near and far scattered field, we used a rigorous method based on the Green's integrals and the extinction theorem (ET) for multiple connected domains [12,[24][25][26][27][28][29][30][31]. In what follows, we summarize the method applied to 2D systems with translation's symmetry, as is the case of the present study.…”

In this work, we show theoretical results of the behaviour of the extinction cross section as a function of the incident wavelength for metallic nanotubes (Nts) with a 2D core-shell structure. To calculate the optical response of the gold, silver and cooper system, an exact integral formalism is implemented. The method is based on Green's integral theorem, and it allows us to compute the electromagnetic field at any point in space. For a correct description of the constitutive parameters of the metallic shell, we introduce a corrective model for the dielectric function in terms of the shell thickness in the range 1 to 10 nm. In particular, we investigate the features of surface plasmons in metallic Nts, and in the cases of Au and Cu, the mechanisms of the interband transitions play a relevant role. In this paper, we show that a quasi-static approach is not sufficient to account the plasmon-plasmon interaction in Ag Nts. The aim of these studies is to characterize core size and shell thicknesses of the Nts by means of the surface plasmon resonance observed in the far field.

“…To investigate such geometries many analytical and numerical approaches were developed. They include, for example, image methods [2][3][4], applications of the extinction theorem [5,6], expansions of cylindrical waves [7,8] or integral-equation methods [9][10][11][12][13]. Most of these methods only consider a background medium consisting of two half spaces [2][3][4][5][6][7][8][9][10][11] or restrict the choice of the material or geometry parameters [2][3][4][5]7].…”

Abstract:We present numerical experiments of light scattering by a circular dielectric cylinder embedded in a stratified background, using the Green's tensor technique. The stratified background consists of two or three dielectric layers, the latter forming an anti-reflection system. We show movies of the scattered field as a function of different parameters: polarization, angle of incidence, and relative position of the cylinder with respect to the background interfaces.
