Photoelectron Spectroscopy and the Dipole Approximation
Over the past three decades, the dipole approximation has facilitated a basic understanding of the photoionization process in atoms and molecules. Advances in gas-phase photoemission experiments using synchrotron radiation have recently highlighted nondipole effects at relatively low photon energies while probing the limits of the dipole approximation. Breakdowns in this approximation are manif...
متن کاملDiscrete-dipole approximation for scattering calculations
The discrete-dipole approximation (DDA) for scattering calculations, including the relationship between the DDA and other methods, is reviewed. Computational considerations, i.e., the use of complex-conjugate gradient algorithms and fast-Fourier-transform methods, are discussed. We test the accuracy of the DDA by using the DDA to compute scattering and absorption by isolated, homogeneous sphere...
متن کاملAccuracy of the discrete dipole approximation for simulation of optical properties of gold nanoparticles
We studied the accuracy of the discrete dipole approximation (DDA) for simulations of absorption and scattering spectra by gold nanoparticles (spheres, cubes, and rods ranging in size from 10 to 100 nm). We varied the dipole resolution and applied two DDA formulations, employing the standard lattice dispersion relation (LDR) and the relatively new filtered coupled dipoles (FCD) approach. The DD...
متن کاملAccurate Computation of Electric Field Enhancement Factors for Metallic Nanoparticles Using the Discrete Dipole Approximation
We model the response of nanoscale Ag prolate spheroids to an external uniform static electric field using simulations based on the discrete dipole approximation, in which the spheroid is represented as a collection of polarizable subunits. We compare the results of simulations that employ subunit polarizabilities derived from the Clausius-Mossotti relation with those of simulations that employ...
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.
