Cascaded plasmon-induced transparency in spoof surface plasmon polariton waveguide

Results in Physics, 2022
Manipulating spoof surface plasmon polaritons (SPPs) effectively has promising applications in developing ultracompact plasmonic circuits. Research on versatile components in planar spoof SPP waveguides has attracted widespread attention over the decades.

Effect of slit width on surface plasmon resonance

Results in Physics, 2019
In this paper, a hybrid resonator composed of an all-metal grating made of copper and a dielectric cavity filled with SiO2 between slits is simulated and calculated by the finite-difference time-domain method (FDTD).

Electrical Excitation of Surface Plasmons [PDF]

Frontiers in Optics 2012/Laser Science XXVIII, 2011
We exploit a plasmon mediated two-step momentum downconversion scheme to convert low-energy tunneling electrons into propagating photons. Surface plasmon polaritons (SPPs) propagating along an extended gold nanowire are excited on one end by low-energy electron tunneling and are then converted to free-propagating photons at the other end.

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 ...

Surface-Enhanced Plasmon Splitting in a Liquid-Crystal-Coated Gold Nanoparticle [PDF]

, 2005
We show that, when a gold nanoparticle is coated by a thin layer of nematic liquid crystal, the deformation produced by the nanoparticle surface can enhance the splitting of the nanoparticle surface plasmon.

Kinetic theory of surface plasmon polariton in semiconductor nanowires

, 2013
Based on the semiclassical model Hamiltonian of the surface plasmon polariton and the nonequilibrium Green-function approach, we present a microscopic kinetic theory to study the influence of the electron scattering on the dynamics of the surface plasmon

Enhancement of Long-Range Surface Plasmon Excitation, Dynamic Range and Figure of Merit Using a Dielectric Resonant Cavity

Sensors, 2018
In this paper, we report a theoretical framework on the effect of multiple resonances inside the dielectric cavity of insulator-insulator-metal-insulator (IIMI)-based surface plasmon sensors.
