      abstract     = {The understanding of flux transport in micro-and
                      nanostructured superconducting systems that are exposed to
                      an electromagnetic field at microwave frequencies is of
                      interest for basic aspects of vortex matter and for
                      potential application of superconductivity in fluxonic
                      devices. We report on the combination of dc and microwave
                      electronic measurements on submicron-patterned high-T-c
                      films. The frequency dependence of the forward transmission
                      coefficient S-21 indicates that the mechanism of flux
                      transport depends on the velocity of vortices. At low
                      frequencies, flux transport via Abrikosov vortices is
                      present leading to additional microwave losses. Above a
                      geometrically defined frequency, a different, loss-free
                      mechanism seems to be responsible for flux transport. This
                      mechanism most likely represents a phase-slip type of
                      mechanism. The limiting vortex velocity obtained from the
                      frequencies dependence of the microwave properties agrees
                      with the Larkin-Ovchinnikov critical vortex velocity
                      determined via dc pulse measurements. In spite of the change
                      of mechanism, guidance of flux persists in these
                      nano-patterns up to high frequencies. (C) 2012 Elsevier B.V.
