(Color online) (a) Pseudodispersion relations for full coupling. Those for cases of homogeneous host with (dash-dotted line) and (dashed line) can be regarded as the usual dispersion relations. (b) Density of states (DOS) vs coupled plasmon mode frequency for the full coupling. The lines with circles represent the results of graded case for nearest-neighboring coupling. (c) Inverse participation ratio (IPR) vs plasmon mode frequency. (d) Typical excitation in low frequency regime . (e) Typical excitation near the resonant frequency . (f) Typical excitation at high frequency .

(c) Analytical (curves) and numerical (symbols) transition frequencies and vs the host gradient coefficient without nonlinearity for different nanoparticle distances . (d) Analytical (curves) and numerical (symbols) transition frequencies vs nonlinearity (pump field) modulation in the host medium, with for different host gradient coefficients and , respectively.
