Surface waves and atomic force microscope probe-particle near-field coupling: discrete dipole approximation with surface interaction
(Optics InfoBase, 2010-10)
Evanescent waves on a surface form due to the collective motion of charges within the medium. They do not carry any energy away from the surface and decay exponentially as a function of the distance. However, if there is ...
Comparison between discrete dipole approximation and other modelling methods for the plasmonic response of gold nanospheres
(Springer Science+Business Media, 2014-05)
We investigate the plasmonic response of gold nanospheres calculated using discrete dipole approximation validated against the results from other discretization methods, namely the finite-difference time-domain method and ...
Enhancing local absorption within a gold nano-sphere on a dielectric surface under an AFM probe
(Elsevier, 2016-07)
This study considers enhancing localized absorption by a gold nanoparticle (NP) placed over a substrate where an atomic force microscope (AFM) tip is in close proximity of the particle. The gold NP and AFM tip are interacting ...
