Plasmon-polaritons on graphene-metal surface and their use in biosensors [PDF]

, 2012
Cataloged from PDF version of article.We studied excitation of surface plasmon-polaritons on graphene-metal surface. The metal surface is functionalized by transfer printing of graphene grown by chemical vapor deposition on copper foils.

Surface Plasmon Resonances of Clustered Nanoparticles [PDF]

Plasmonics, 2011
Linear clusters made by tightly connecting two or more metallic nanoparticles have new types of surface plasmon resonances as compared to isolated nanoparticles. These new resonances are related to the size of the junction and to the number of interconnected particles and have direct interpretation as eigenmodes of a Boundary Integral Equation (BIE ...

Plasmon resonance studies of iron coated gold films with and without an applied magnetic field

AIP Advances, 2017
Surface plasmon excitations can result from the absorption of light incident on gold films. Adding a ferromagnetic metal, in our case iron, allows the surface plasmon resonance peak energy to be manipulated not only by the free electrons present in ...

Giant THz surface plasmon polariton induced by high-index dielectric metasurface

, 2017
We use computational approaches to explore the role of a high-refractive-index dielectric TiO2 grating with deep subwavelength thickness on InSb as a tunable coupler for THz surface plasmons.

Determination of thickness and dielectric constant of thin transparent dielectric layers using surface plasmon resonance [PDF]

, 1991
The determination of the thickness and dielectric constant of thin dielectric layers by means of surface plasmon resonance is discussed. It appears to be impossible to determine these parameters from one surface plasmon response experiment.

Sensitivity comparison of surface plasmon resonance and plasmon-waveguide resonance biosensors [PDF]

Sensors and Actuators B: Chemical, 2011
Plasmon-waveguide resonance (PWR) sensors are particularly useful for investigation of biomolecular interactions with or within lipid bilayer membranes. Many studies demonstrated their ability to provide unique qualitative information, but the evaluation of their sensitivity as compared to other surface plasmon resonance (SPR) sensors has not been ...
