Discrete dipole approximation of gold nanospheres on substrates: considerations and comparison with other discretization methods
(AAPP Physical, Mathematical, and Natural Sciences, 2011)
We embark on this preliminary study of the suitability of the discrete dipole approximation with surface interaction (DDA-SI) method to model electric field scattering from noble metal nano-structures on dielectric substrates. ...
Dependent absorption and scattering by interacting nanoparticles
(Begell House Inc., 2010)
Dependent light scattering and absorption patterns of metallic nano-sized particles in interaction with other spherical and cone-like structures were investigated. The numerical solution of the light scattering problem was ...
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 ...
Spectral tuning of near-field radiative heat flux between two thin silicon carbide films
(Institute of Physics, 2010)
Spectral distributions of radiative heat flux between two thin silicon carbide films separated by sub-wavelength distances in vacuum are analysed. An analytical expression for the near-field flux between two layers of ...
A biomimicry design for nanoscale radiative cooling applications inspired by Morpho didius butterfly
(Nature Publishing Group, 2018-11-15)
In nature, novel colors and patterns have evolved in various species for survival, recognizability or mating purposes. Investigations of the morphology of various butterfly wings have shown that in addition to the pigmentation, ...
Discrete-dipole approximation with surface interaction: computational toolbox for MATLAB
(Elsevier, 2011-07)
We describe a MATLAB toolbox that utilizes the discrete-dipole approximation (DDA) method for modelling light interaction with arbitrarily-shape scatterers in free space as well with planar surface interaction (DDA-SI). ...
Integrating magnetic heads with plasmonic nanostructures in multilayer configurations
(IEEE, 2013-07)
Heat-assisted magnetic recording (HAMR) is an emerging technology that has increased the areal density of conventional recording techniques for hard disc drives. Integrated heads have enabled this increase through localized ...
Radiative transfer configuration factor catalog: a listing of relations for common geometries
(Elsevier, 2011-03)
An on-line compilation of radiation configuration factors for over 300 common geometries is provided as a supplementary material from the JQSRT web site at doi:10.1016/j.jqsrt.2010.10.002. The factors are gathered from ...
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 ...
Design, operation, and motion characteristics of a precise piezoelectric linear motor
(Elsevier, 2010-04)
This paper presents the design, operation, and motion characteristics of a precise piezoelectric motor for linear translation. The motor is compact, thermally stable, ultra-high vacuum compatible, and suitable for applications ...
