Efficient plasmonic coupling between Er3+:(Ag/Au) in tellurite glasses
(Elsevier B.V., 2012-01-15)
We report a systematic study of the localized surface plasmon resonance effects on the photoluminescence of Er3+-doped tellurite glasses containing Silver or Gold nanoparticles. The Silver and Gold nanoparticles are obtained ...
Critical coupling of surface plasmons in graphene attenuated total reflection geometry
(Elsevier Science, 2016-11)
We study the optical response of an attenuated total reflection (ATR) structure in Otto configuration with graphene sheet, payingespecial attention to the occurrence of total absorption. Our results show that due to ...
Production of surface plasmons in electron emission from Al nanoparticles
(Elsevier, 2014-05)
In this work we study the surface plasmon generation by a suddenly created electron-hole pair in nanoparticles of spherical shape. We use a previously developed model based on the Hamiltonian formulation for plasmon field.
Plasmonic Interactions: From Molecular Plasmonics and Fano Resonances to Ferroplasmons
(American Chemical Society, 2014-10)
Plasmon interactions are a subject of great interest from both the technological as well as the fundamental points of view. In this Perspective, we outline the great variety of physical phenomena that are produced by the ...

Coupled plasmonic graphene wires: theoretical study including complex frequencies and field distributions of bright and dark surface plasmons
(Optical Society of America, 2020-10)
Theoretical research on localized surface plasmons (LSPs) supported by a structure formed by two parallel dielectric wires with a circular cross section wrapped with a graphene sheet has an impact in the practical realm. ...
Near field evidence of backward surface plasmon polaritons on negative index material boundaries
(Elsevier Science, 2016-12)
We present a detailed analysis about the electromagnetic response of a metamaterial surface with a localized defect. The excitation of electromagnetic surface waves leads to a near-field distribution showing a periodic ...
