Abstract
We investigate the plasmonic response of gold nanospheres calculated using discrete dipole approximation validated against the results from other discretization methods namely the finitedifference timedomain method and the finiteelement methods Comparisons are also made with calculations from analytical methods such as the Mie solution and the nullfield method with discrete sources We consider the nanoparticle interacting with the incident field both in free space and sitting on a planar substrate In the latter case discrete dipole approximation with surface interaction is used this includes the interaction with the ‘image dipoles’ using Sommerfeld integration
