We present measurements on plasmonic meta-molecules under local excitationusing cathodoluminescence which show a spatial redistribution of the localdensity of optical states (LDOS) at the same frequency where a sharp spectralFano-feature in the extinction cross section has been observed. Our analyticalmodel shows that both near- and far-field effects arise due to interference ofthe same two eigenmodes of the system. We present quantitative insights both ina bare state, and in a dressed state picture that describe plasmonic Fanointerference either as near-field amplitude transfer between three coupled barestates, or as interference of two uncoupled eigenmodes in the far field. Weidentify the same eigenmode causing a dip in extinction to strongly enhance theradiative LDOS, making it a promising candidate for spontaneous emissioncontrol.
