Why the aspect ratio? Shape equivalence for the extinction spectra of gold nanoparticles

My paper just got published in The European Physical Journal E !


In it, I argue that when describing elongated gold nanoparticles as ellipsoids (to the purpose of modelling their light extinction spectra) the natural comparison criterion is the equivalence of the various moments of mass distribution, rather than the length-to-diameter (aspect) ratio generally used in the literature. I also show that it leads to better spectral correspondence between the various shapes.
