Tunable plasmonic enhancement of light scattering and absorption in graphene-coated subwavelength wires
(IOP Publishing, 2015-07)
The electromagnetic response of subwavelength wires coated with a graphene monolayer illuminated by a linearly polarized plane waves is investigated. The results show that the scattering and extinction cross-sections of ...
Complex frequencies and field distributions of localized surface plasmon modes in graphene-coated subwavelength wires
(Pergamon-Elsevier Science Ltd, 2016-04)
In this work we study the modal characteristics of localized surface plasmons in graphene-coated, circular cross-section wires. Localized surface plasmons are represented in terms of cylindrical multipole partial waves ...
Study of Er3+ fluorescence on tellurite glasses containing Ag nanoparticles
(2011-04-12)
Optical characteristics of tellurite glasses containing silver nanoparticles (NPs) and the influence on the emission spectrum of Er 3+ ions were studied. The transitions 4f ↔ 4f from erbium ions, mainly the 4I13/2 → 4I15/2 ...

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 ...
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 ...
