Femtosecond Autocorrelation of Localized Surface Plasmons [PDF]

open access: yesNanomaterials, 2023
Plasmon electronic dephasing lifetime is one of the most important characteristics of localized surface plasmons, which is crucial both for understanding the related photophysics and for their applications in photonic and optoelectronic devices.

Magnetic Localized Surface Plasmons [PDF]

open access: yesPhysical Review X, 2014
Here, we introduce the concept of magnetic localized surface plasmons (LSPs), magnetic dipole modes that are supported by cylindrical metal structures corrugated by very long, curved grooves.

Localized Surface Plasmons in Vibrating Graphene Nanodisks [PDF]

open access: yesNanoscale, 2016
Localized surface plasmons are confined collective oscillations of electrons in metallic nanoparticles. When driven by light, the optical response is dictated by geometrical parameters and the dielectric environment and plasmons are therefore extremely ...

Localized surface plasmons in structures with linear Au nanoantennas on a SiO2/Si surface [PDF]

open access: yesBeilstein Journal of Nanotechnology, 2016
The study of infrared absorption by linear gold nanoantennas fabricated on a Si surface with underlying SiO2 layers of various thicknesses allowed the penetration depth of localized surface plasmons into SiO2 to be determined.

Charge reservoir as a design concept for plasmonic antennas [PDF]

open access: yesNanophotonics
Plasmonic antennas exploit localized surface plasmons to shape, confine, and enhance electromagnetic fields with subwavelength resolution. The field enhancement is contributed to by various effects, such as the inherent surface localization of plasmons ...

Localized surface plasmons of gold nanoparticles

open access: yesSt. Petersburg Polytechnical University Journal: Physics and Mathematics, 2022
In this paper, gold nanoparticle far-field and near-field optical responses are studied and simulated numerically. The electromagnetic field was excited by an electric dipole near one end of the nanorod, which is used to model the emission of a quantum ...
