Calibrated dispersion curves are obtained over a wavelength range spanning from 550 to 900 nm. We obtain good qualitative agreement with calculated dispersion curves that take into account the thickness of the thin film.plasmonsspectroscopythin filmsDirect imaging of surface plasmon polariton dispersion in gold and silver thin filmstext::journal::journal article::research article
