Abstract

We consider the influence of quasiparticle relaxation and nonlocality on the complex conductivity and microwave surface impedance of isotropic and quasi-two-dimensional metals in the normal and superconducting states for arbitrary electronic parameters intermediate between the classical skin effect and extreme anomalous limits. We describe the superconducting state by a two-fluid model with a nonlocal, retarded quasiparticle response and derive an expression for the surface impedance at low temperatures in the extreme anomalous limit. We show how microwave measurements can be used to probe the k dependence of the superconducting order parameter in layered materials.
