The small particle limit is also investigated. We compute the extinction cross section of a negative index sphere, as well as intensity maps. Excitation of surface plasmons featuring narrow linewidths is observed, which can be attributed to the permitivity or the permeability of the sphere. %G English %L hal-02460766 %U https://utt.hal.science/hal-02460766 %~ CNRS %~ UNIV-TROYES %~ UTT
