• aggregates respond to an effective wavelength λeff [18] rather than the wavelength λ of the incident radiation, according to: where λp is the plasmon wavelength, and n1 and n2 are proper geometrical constants also depending upon static dielectric properties [18]. Since light localization is due to the
