Frohlich resonance
WebEvolution of the (Fröhlich) surface-resonance associated with the π resonance of Rayleigh-sized polycrystalline grains as the average relative number, s , of graphene layers per stack... WebAbove the Frohlich resonance (at smaller wavelengths), the spectral variable Re(a3/α) becomes negative. (Here we ignore the region λ<320nm where no resonance excitation can take place due to the strong interband absorption.) Therefore, in order to excite a SP in an interacting ODPC in this spectral region, the variable ReSmust be also ...
