Absorption suppression of silver nanoparticles in the presence of an AFM tip: A harmonic oscillator model
(AIP, 2012)We numerically calculated the optical absorption of silver nanoparticles (AgNP) in the presence of metallic and dielectric AFM probes, illuminated by transverse magnetic (TM) polarized, total internal reflected waves. ... -
Discrete dipole approximation with surface interaction
(Elsevier, 2023-01-01)In this chapter, we discuss a methodology to determine absorption and scattering cross sections of particles of different size and shape placed on substrates. This approach is based on the principles of discrete dipole ... -
Effect of the probe location on the absorption by an array of gold nano-particles on a dielectric surface
(Elsevier, 2017)Effect of silicon atomic force microscope probe position and particle spacing on the local absorption of an array of gold nanoparticles placed over a dielectric borosilicate glass surface are evaluated. An improved, ... -
Estimating quantitative features of nanoparticles using multiple derivatives of scattering profiles
(Elsevier, 2011-05)Characterization of nanoparticles on surfaces is a challenging in verse problem whose solution has many practical applications. This article proposes a method, suitable for in situ characterization systems, for estimating ...
