Dielectric Function
so how should this be done for the FD distribution. Should it be E(p + q) ~ p^2 + q^2 ?
also hw = h*c*q would only hold for a free solution of maxwell equations in the medium. [/QUOTE]
but how do we know the relationship between q and w if we donīt yet know the refractive index?[/QUOTE]
