Plasmon resonances in a quartz nanofiber coated with a silver layer

Symmetrical and nonsymmetrical excitation of plasmon oscillations in clusters consisting of two 6H-SiC cylinders

“…The boundary-value problem was numerically solved by the modified discrete source method [11][12][13]. The accuracy of the numerical solution was estimated by residual Δ of the boundary conditions on contours of the cylinders and it was less then Δ<10 -3 for all obtained results.…”

“…Note that such nanowires are used in spectroscopy and are also used as sensors or nano antennas. Plasmon resonances in clusters formed by two or three silver nanocylindres (spheres) were considered in [8][9][10][11][12][13]. We have to stress that plasmons and their resonances exists not only at the boundary of such plasma-like media as silver or gold.…”

Localized versus delocalized surface plasmons: dual nature of optical resonances on a silver circular wire and a silver tube of large diameter

“…In computations, we do not use the Drude formula for the dielectric function of silver, because it provides grossly incorrect values of Re ε M (λ) and especially Im ε M (λ) in the violet range where all LSP modes of the solid silver wire and some of the hybrid LSP modes of the circular silver nanotube are located (see e.g. [16][17][18]). Instead, we take the experimental data of Johnson and Christy [2], widely recognized as reliable [22], and use the Akima spline interpolation algorithm to obtain ε M (λ) at any λ.…”

“…Besides solid wires, even more intensive transverse LSP resonances are known in the scattering and absorption of light by noble-metal tubes having nanoscale thickness [11][12][13][14][15][16][17]. Such nanotubes are commonly used in optical sensors [18,19].…”
