THE OPTICS OF SURFACE PLASMONS

open access: yesLe Journal de Physique Colloques, 1984
We have studied numerically the reflection, transmission, and conversion to radiation fields of surface polaritons or radiation fields incident (a) onto the end face of a polariton active medium or (b) from one polariton active medium to another separated by a variable width barrier.

High-Performance coupled plasmon waveguide resonance optical sensor based on SiO2:Ag film

open access: yesResults in Physics, 2021
A coupled plasmon waveguide resonance (CPWR)-based optical sensor takes advantage of the evanescent wave at a waveguide boundary to excite surface plasmon polaritons, which can link waveguide electromagnetic energy to a surface plasmon wave to enhance ...

Harvesting the loss: surface plasmon-based hot electron photodetection

open access: yes, 2017
Although the nonradiative decay of surface plasmons was once thought to be only a parasitic process within the plasmonic and metamaterial communities, hot carriers generated from nonradiative plasmon decay offer new opportunities for harnessing ...

Eco‐Fabricated Nanowave‐Textured Implants Drive Microtubule‐Assisted Nuclear Mechanotransduction and Chromatin Modification: Biophysical Priming for Osteogenesis and Bone Regeneration

open access: yesAdvanced Functional Materials, EarlyView.
Eco‐friendly nanowave‐textured implants produced via femtosecond laser fabrication enhance bone regeneration by orchestrating a precise mechanotransduction cascade. This nanotopography directs mesenchymal stem cell alignment and cytoskeletal organization, triggering changes in nuclear shape and chromatin acetylation that prime cells for osteogenesis ...

Surface Plasmon Resonance Sensors on Raman and Fluorescence Spectroscopy

open access: yesItalian National Conference on Sensors, 2017
The performance of chemical reactions has been enhanced immensely with surface plasmon resonance (SPR)-based sensors. In this review, the principle and application of SPR sensors are introduced and summarized thoroughly. We introduce the mechanism of the

Nonlinear surface plasmons

open access: yes, 2015
We derive an asymptotic equation for quasi-static, nonlinear surface plasmons propagating on a planar interface between isotropic media. The plasmons are nondispersive with a constant linearized frequency that is independent of their wavenumber. The spatial profile of a weakly nonlinear plasmon satisfies a nonlocal, cubically nonlinear evolution ...

Au@h‐BN Core–Shell Nanostructure as Advanced Shell‐Isolated Nanoparticles for In Situ Electrochemical Raman Spectroscopy in Alkaline Environments

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates the stability and Raman signal enhancement effects of Au@h‐BN nanoparticles in an alkaline electrolyte on. A comparison between conventional SiO2 and h‐BN shells reveals that the h‐BN core‐shell structure provides superior stability and enhanced Raman intensity over multiple cyclic voltammetry cycles.

Pearcey plasmon: An autofocusing surface wave

open access: yesResults in Physics, 2021
In this article, we present a new kind of autofocusing surface plasmonic wave: the Pearcey plasmon. The result shows that the Pearcey plasmon evolves at the silver-air interface in the form of two-dimensional Pearcey plasmon function.

Nanomaterials enhanced surface plasmon resonance for biological and chemical sensing applications.

open access: yesChemical Society Reviews, 2014
The main challenge for all electrical, mechanical and optical sensors is to detect low molecular weight (less than 400 Da) chemical and biological analytes under extremely dilute conditions.
