摘要：

Prompted by the growing interest in the optical properties of coupled metal nanoclusters, we implemented a code in the framework of Generalized Multiparticle Mie theory (GMM) to simulate far-field properties of strongly interacting spherical particles. In order to validate the code different case studies, including systems modeled for the first time, have been treated. The extinction properties of noble metal nanocluster dimers, chains and core-satellite structures have been computed. Influence of parameters like interparticle distance, incident field polarization, number of multipolar expansions and chain length has been studied. The code provided reliable results in agreement with previous works and proved to be affordable and robust in any of the treated case. (c) 2006 Elsevier B.V. All rights reserved.
