In this paper the surface impedance, Z{sub s}, is calculated for type-II superconductors subjected to a static magnetic field and small-amplitude microwave radiation. A complex penetration depth is calculated by using a model of vortex dynamics including a linear pinning restoring force and a viscous drag force. The static magnetic field dependence of the surface resistance R{sub s} and surface reactance X{sub s} is found by examining the dependence of the complex penetration depth on the length scales for low-field penetration, pinning penetration, and flux-flow penetration. In turn, from R{sub s}, the static magnetic field dependence of the rate of energy dissipation is found.
