Resumen:
A resonance condition has been obtained for the position of plasmon peaks of any multipole order in theextinction spectra of silver and gold nanorods, as a function of their material, size, shape, and dielectricenvironment. The expression has been derived combining electrodynamics simulations with the aid of ananoantenna-standing wave model approach. Some scaling laws, emerging from the above expression, arealso demonstrated, in very good agreement with recent experiments and theoretical studies.
