Comments on "Surface plasmon resonance of metal nanoparticles sandwiched between dielectric layers: theoretical modeling".
The Maxwell-Garnett's and Toudert's methods detailed in Appl. Opt.48, 778 (2009)APOPAI0003-693510.1364/AO.48.000778, based on the Maxwell-Garnett and Yamaguchi effective medium models, respectively, have been used for calculating the absorbance alpha of a (BaF(2)/Ag)(5)/BaF(2) nanocomposite thin film identical to the one presented in Fig. 1 of Appl. Opt.48, 778 (2009)APOPAI0003-693510.1364/AO.48.000778]. We propose that the discrepancies observed in this reference between the alpha spectra calculated by the two methods are due to a non rigorous use of both effective medium models by the author and show that adequate calculations lead to superposed spectra.
