The localized surface plasmon resonances of silver nanoparticles are explored by applying numerical full-wave electrodynamic simulations. In this work the plasmonic response of spherical, cubic and cylindrical rod-shaped silver nanoparticles, and shapes varying continuously between them are presented. The electrodynamic characterization is done by their extinction, albedo, and the corresponding resonant surface field distributions. Several shape effects on the plasmonic resonances are elucidated, enabling the proper adjustment of their response for application-oriented purposes.
