An intraband transition is a transition between electronic states within the same band (intra- is a Latin word meaning ‘within’ ). For instance, there is a filled d band below the Fermi energy in noble metals used in plasmonics, and a partially filled s band where the Fermi energy is located.

Different from interband transitions, intraband transitions are an unavoidable consequence of coupling light to free carriers and are modelled by a loss parameter in the Drude function.
