A Poincaré's approach for plasmonics: the plasmon localization
Journal of Microscopy, 2008SummaryA Poincaré's approach is employed to characterize the excitation of a plasmon, which in essence corresponds to a zero of a complex S‐matrix. Throughout this work we study the plasmonic behaviour of gold, as this metal not only is frequently used in experimental arrays, but also requires an accurate dispersion model to properly excite plasmons ...

Focusing Surface Plasmons with a Plasmonic Lens
Nano Letters, 2005We report the focusing of surface plasmon polaritons by circular and elliptical structures milled into optically thick metallic films or plasmonic lenses. Both theoretical and experimental data for the electromagnetic nearfield is presented. The nearfield is mapped experimentally using nearfield scanning optical microscopy and plasmonic lithography. We

Light is a wonderful medium for carrying information. Optical fibers now span the globe, guiding light signals that convey voluminous streams of voice communications and vast amounts of data. This gargantuan capacity has led some researchers to prophesy that photonic devices--which channel and manipulate visible light and other ...

Annual Review of Analytical Chemistry, 2016
In this review, we survey recent advances in the field of molecular plasmonics beyond the traditional sensing modality. Molecular plasmonics is explored in the context of the complex interaction between plasmon resonances and molecules and the ability of molecules to support plasmons self-consistently.

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.

Advanced Materials, 2013
AbstractPlasmonics has developed into one of the rapidly growing research topics for nanophotonics. With advanced nanofabrication techniques, a broad variety of nanostructures can be designed and fabricated for plasmonic devices at nanoscale. Fundamental properties for both surface plasmon polaritons (SPP) and localized surface plasmons (LSP) arise a ...
