Sol-Gel Thin Films for Plasmonic Gas Sensors

open access: yesSensors, 2015
Plasmonic gas sensors are optical sensors that use localized surface plasmons or extended surface plasmons as transducing platform. Surface plasmons are very sensitive to dielectric variations of the environment or to electron exchange, and these effects

Excitation of Surface Plasmons by Inelastic Electron Tunneling

open access: yesFrontiers in Physics, 2020
Surface plasmons are usually excited by diffraction-limited optical methods with the use of bulky optical components, which greatly limits the miniaturization and chip-scale high-density integration of plasmonic devices.

Designing Plasmonic Gratings with Transformation Optics

open access: yesPhysical Review X, 2015
Plasmonic gratings that support both localized and propagating plasmons have wide applications in solar cells and optical biosensing. In this paper, we report on a most unusual grating designed to capture light efficiently into surface plasmons and ...

Universal slow plasmons and giant field enhancement in atomically thin quasi-two-dimensional metals [PDF]

open access: yes, 2020
Plasmons depend strongly on dimensionality: while plasmons in three-dimensional systems start with finite energy at wavevector q = 0, plasmons in traditional two-dimensional (2D) electron gas disperse as ωp∼q√. However, besides graphene, plasmons in real,

Tunable plasmonic enhancement of light scattering and absorption in graphene-coated subwavelength wires [PDF]

open access: yes, 2015
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 extintion cross-sections of the coated wire can be dramatically

Investigation of surface plasmons in Kretschmann structure loaded with a silver nano-cube

open access: yesResults in Physics, 2019
A composite structure based on a Kretschmann structure loaded with silver nano-cube is proposed. A 442-nm laser was used to excite surface plasmons in the composite structure, and the electric field enhancement was numerically simulated using the finite ...

Near-field enhancement by waveguide-plasmon polaritons in a nonlocal metasurface

open access: yesNew Journal of Physics, 2023
Localized surface plasmons in metal nanoparticles are widely used in nano-optics to confine and enhance optical fields. It has been previously shown that, if the nanoparticles are distributed periodically, an additional enhancement can be achieved by ...
