The Drude model provides a useful phenomenological approach for the discussion of the metallic properties in conducting materials, particularly from the perspective of their electrodynamic response. We first introduce the model and its generalization, which accounts for the frequency dependence of the scattering rate and effective mass of the quasiparticles. Three selected examples, from the optical research on the topic of strongly correlated metals, will illustrate the variety of issues and broad spectrum of informations, which can be addressed and achieved within this approach.
