Dispersion relation for plasmon polaritons and map of electromagnetic modes for Drude MDN without scattering. (a) Dispersion relation for plasmon polaritons at ωp = 1016 s−1, g = 0.1 and ϵd = 3.42 (blue line). The light line ω = ck is also shown. (b) Map of the electromagnetic modes in the g-ω plane. SPP and BPP exist in gray and hatched areas, respectively.
