Abstract
The response of coupled metallic nanoparticles of various shapes to excitations by plane waves and an electron beam is investigated numerically within an efficient eigenvector expansion of the discrete-dipole approximation (DDA). It is shown that this procedure allows to reduce significantly the size of the system of equations to be solved (hence the computationnal effort) when one considers multiparticle systems. The results are then confronted to standard DDA for validation.
