Surface-plasmon dispersion and multipole surface plasmons in Al(111)
Physical Review B, 2000We have measured the collective electronic excitations of the Al(111) surface by means of angle-resolved high-resolution electron-energy-loss spectroscopy. Loss spectra reveal both the monopole and the multipole surface plasmons. The measured dispersion of the monopole surface plasmon is negative, as predicted by calculations of the dynamic response of

Surface Plasmons and Plasmonics
2020Surface plasmons (SPs) correspond to self-sustaining excitations of the electron gas of metals or semiconductors, i. e., to modulations of the density of such gas occurring at the surface of the body generating electric fields propagating along the surface and decaying exponentially perpendicular to it.

Abstract In this chapter, the classical Drude model is used to understand the basic mechanism of plasma wave generation and sub-wavelength propagation, the concept of plasma frequency, the nature of variation of dielectric function, the dispersion relation of surface plasmons in metal-insulator and metal-insulator-metal structures ...

Summary form only given. With modern nanofabrication techniques, surface plasmons can be engineered and controlled to yield unique optical properties which suggest many applications. This potential is well illustrated by the surface plasmon induced novel properties of subwavelength apertures.

Interaction between surface plasmons and localized plasmons
Physical Review B, 1985A theoretical analysis of the experiments of Holland and Hall [Phys. Rev. B 27, 7765 (1983)] is given. The metal-island film is characterized by an effective anisotropic dielectric function. Formulas for reflection and transmission coefficients for an anisotropic layered structure are given.

Hybrid of graphene surface plasmons and surface magneto-plasmons in a waveguide
Superlattices and Microstructures, 2020Abstract The terahertz frequency has potential applications in various devices, and surface plasmons open up a number of promising applications. With the motivation of studying the possibility of hybridization of different surface plasmons, we proposed a waveguide structure with magneto-optical and dielectric layers with an air spacer layer in which ...

Focusing surface plasmons by a plasmonic lens
SPIE Proceedings, 2014Surface plasmons have been launched from free space optical beams (at an excitation wavelength of 700 nm) and focused in the plane using concentric curved gratings (or plasmonic lenses) etched into 30 nm-thick gold films. The performance of these devices was studied with numerical simulation and verified by near-field scanning optical microscopy ...

Surface Plasmon Resonance for Proteomics
2011Surface plasmon resonance (SPR) is a well-established label-free technique to detect mass changes near an SPR surface. For 20 years the benefits of SPR have been proven in biomolecular interaction analysis, including measurements of affinity and kinetics.

Slowing Down Surface Plasmons on a Moiré Surface
Physical Review Letters, 2009We have demonstrated slow propagation of surface plasmons on metallic Moiré surfaces. The phase shift at the node of the Moiré surface localizes the propagating surface plasmons and adjacent nodes form weakly coupled plasmonic cavities. Group velocities around v_{g}=0.44c at the center of the coupled cavity band and almost a zero group velocity at the ...
