Abstract
We calculate the complex conductivity of a superconducting thin film in a tilted magnetic field. Use is made of the time-dependent Ginzburg-Landau equations to deal with the dynamical behavior of the order parameter associated with the vortex motion in response to the microwave. The reactive part of the conductivity at zero frequency vanishes identically due to the vortex motion and the conductivity resembles that in the flux-flow regime of the type-II superconductor, unless the dc magnetic field is parallel to the film surface with high precision.
