what is the wavelenght of SPR wave in structure in nm unit? is that equal whit plasma frequency wp?
Each size and shape nanoparticle represents a different resonance frequency. For more information about resonance these web sites may help.

In the first animation when the force applied matches the maximum spring constant resonance occurs. Similarly, when the wavelength frequency matches the resonance energy maximum oscillation of the plasmons occur.
spp wavelength < wavelength of the excitation
