Optical forces induced by metal nanoparticle clusters

The strong field localization generated between closely placed metal particles excited by radiation induces intense forces on small polarizable objects. In this study we investigated the optical forces that can be generated in the vicinity of metal nanoparticle clusters using fully electrodynamic numerical simulations. The influence of the cluster configuration (material, numer of particles and geometrical arrangement) as well as the excitation parameters (polarization distribution and degree of focusing) is investigated
