Surface plasmon

2022
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 ...

Surface Plasmons and Plasmonics

2020
Surface 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.

Surface plasmon photonics

Infrared and Millimeter Waves, Conference Digest of the 2004 Joint 29th International Conference on 2004 and 12th International Conference on Terahertz Electronics, 2004., 2006
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.

Hybrid of graphene surface plasmons and surface magneto-plasmons in a waveguide

Superlattices and Microstructures, 2020
Abstract 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, 2014
Surface 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

2011
Surface 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.

Semiconductor Surface Plasmon Sources

Physical Review Letters, 2010
Surface-plasmon polaritons (SPPs) are propagating electromagnetic modes bound at a metal-dielectric interface. We report on electrical generation of SPPs by reproducing the analogue in the near field of the slit-doublet experiment, in a device which includes all the building blocks required for a fully integrated plasmonic active source: an electrical ...

Measuring group velocity of surface plasmons by surface plasmon interferometry

2007 Quantum Electronics and Laser Science Conference, 2007
Broadband optical transmission spectra of metal films with subwavelength slit-groove pairs show pronounced interference fringes by surface plasmons travelling between slits and grooves. Interferometric fringe analysis provides accurate values for group velocity of surface plasmons.

Surface plasmons on rough surfaces

Il Nuovo Cimento B Series 11, 1977
Experiments with surface plasmons on rough and sinusoidally corrugated surfaces of metals with quasi-free electrons are performed to study the changes of the dispersion relation. The result is that the eigenfrequency of the plasma oscillations is displaced and the damping is increased. The dependence of the displacement and of the damping on the height
