Theory of surface plasmons and surface-plasmon polaritons [PDF]
Reports on Progress in Physics, 2006 Collective electronic excitations at metal surfaces are well known to play a key role in a wide spectrum of science, ranging from physics and materials science to biology. Here we focus on a theoretical description of the many-body dynamical electronic response of solids, which underlines the existence of various collective electronic excitations at ...

Surface effects on bulk plasmons [PDF]
Physical Review B, 1993 We discuss the effects of surfaces on bulk plasma oscillations in a metallic film of thickness $L$. The leading corrections to the plasma frequencies due to the surfaces are proportional to $L^{-1}$. dispersion relation of bulk modes, $ω=ω_p[1+α(q^2/k_F^2)] $, where the allowed $q$-values are $q^{(n)}=(nπ/\overline L)$, $\overline L\equiv L-2d_b$, and $

Surface Plasmon Radiation Forces [PDF]
Physical Review Letters, 2006 We report the first experimental observation of momentum transfer from a surface plasmon to a single dielectric sphere. Using a photonic force microscope, we measure the plasmon radiation forces on different polystyrene beads as a function of their distance from the metal surface.

Optimization of plasmon–plasmon coupling in photorefractive layered media [PDF]
, 2013 In this paper we study grating-induced plasmon–plasmon coupling in photorefractive layered media using a weakcoupling approximation. The method used is applicable to general layered structures that support both plasmonic and optical modes, such as ...

Development of a combined surface plasmon resonance/surface acoustic wave device for the characterization of biomolecules [PDF]
, 2009 It is known that acoustic sensor devices, if operated in liquid phase, are sensitive not just to the mass of the analyte but also to various other parameters, such as size, shape, charge and elastic constants of the analyte as well as bound and viscously

SPRD: a surface plasmon resonance database of common factors for better experimental planning
BMC Molecular and Cell Biology, 2021 Background Surface plasmon resonance is a label-free biophysical technique that is widely used in investigating biomolecular interactions, including protein-protein, protein-DNA, and protein-small molecule binding.

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.
