      abstract     = {We report on combined dc and microwave electronic
                      measurements of magnetic flux transport in micron and
                      submicron-patterned high-T-c films. In a given temperature
                      regime below the superconducting transition temperature T-c,
                      the current-driven flux transport is restricted to flux
                      motion guided by the submicron patterns. Via
                      frequency-dependent measurements of the forward transmission
                      coefficient S-21 it is demonstrated that the mechanism of
                      the guided flux transport depends on the microwave frequency
                      and the geometrical size of the superconducting structures.
                      At low frequencies, flux is transported via Abrikosov
                      vortices leading to additional microwave losses. Above a
                      geometrically defined frequency, a different mechanism seems
                      to be responsible for flux transport that does not
                      contribute to the microwave losses and most likely
                      represents a phase-slip type mechanism. The limiting vortex
                      velocity obtained from the frequency dependence of the
                      microwave properties agrees with the Larking-Ovchinnikov
                      critical vortex velocity that is determined via dc pulse
                      measurements. In spite of the change of mechanism, guidance
                      of flux persists in these nanopatterns up to high
                      frequencies of several GHz.},
