Definition

A classical model of electrical and optical response in metals that treats conduction electrons as a noninteracting gas of classical particles subject to randomizing scattering events characterized by an average scattering time τ; it yields a DC conductivity proportional to the product of carrier density and scattering time and a frequency-dependent response featuring a plasma-like behaviour for i
