Comparison of multiple scattering theory and effective medium theory. (a), (b), (c) Dispersion curves obtained from multiple scattering (M.Scat) and extended Maxwell-Garnett effective medium theory (EMT) for silver nanoparticle array with volume fractions of 0.1, 0.3 and 0.5, respectively. (d), (e), (f) Real and imaginary parts of the effective permittivity calculated by the extended Maxwell-Garnett effective medium for silver volume fractions of 0.1, 0.3 and 0.5, respectively (From Ref. [49]).
