Perturbations of Dipole Decay Dynamics Induced by Plasmonic Nano-antennas – A Study within the Discrete Dipole Approximation
We report a discrete dipole approximation approach to analyse the perturbations induced by silver nano-particles on the decay dynamics of a point-like emitter placed in their proximity. Due to the excitation of localized surface plasmons, metallic nano-particles behave like optical antennas and are able to convert localized fields into freepropagating optical radiation, and vice versa. Field lo...
متن کاملCalculation of the Induced Charge Distribution on the Surface of a Metallic Nanoparticle Due to an Oscillating Dipole Using Discrete Dipole Approximation method
In this paper, the interaction between an oscillating dipole moment and a Silver nanoparticle has been studied. Our calculations are based on Mie scattering theory and discrete dipole approximation(DDA) method.At first, the resonance frequency due to excitingthe localized surface plasmons has been obtained using Mie scattering theory and then by exciting a dipole moment in theclose proximity of...
متن کاملVector diffraction analysis by discrete-dipole approximation.
The discrete-dipole approximation is applied to vector diffraction analysis in a system with large-numerical-aperture (NA) optics and subwavelength targets. Distributions of light diffracted by subwavelength dielectric targets are calculated in a solid angle that corresponds to a NA of 0.9, and their dependence on incident polarization, target shape, and target size is studied. Electric field d...
متن کاملImprovements of the Discrete Dipole Approximation method
We report improvements in complex conjugate gradient algorithms applied to the discrete dipole approximation (DDA). It is shown that computational time is reduced by using the BiCGSTAB version of the CG algorithm, with diagonal left preconditioning.
متن کاملValidity criteria of the discrete dipole approximation.
There are two widely accepted restrictions on the application of the discrete dipole approximation (DDA) in the study of light scattering by particles comparable to the wavelength: (1) when considering dielectric particles, the size of the cells must satisfy the condition kd|m|<0.5, where k is the wavenumber, d is the size of the cells, and m is the complex refractive index of the constituent m...
