We note that the analysis in expands the whole scattered field in the Taylor approximation, mixing together the different Mie spherical harmonics. Although this procedure eventually ensures numerical convergence, it requires a much higher number of terms in order to predict the correct results near the resonance of the nanoparticle, similar to the cases considered here. This explains the disagreement between our full-wave results and the approximate calculation in . Also contrary to the claim mentioned in that a correct evaluation of the power-flow distribution would require multiple Mie orders, we believe that this is not the case, in the sense that, even if in their Taylor expansion higher-order terms are needed, with a full-wave Mie harmonic expansion one would require one single resonant harmonic to predict the overall power distribution, as has been shown here.
