      abstract     = {The new fourth-generation synchrotron radiation source
                      PETRA IV at DESY (Hamburg) will use a fast orbit feedback
                      system to meet stringent orbit stability requirements. To
                      this end, hundreds of fast orbit corrector magnets will be
                      installed to minimize orbit distortions from external
                      sources. These magnets are operated at high frequencies,
                      creating strong eddy currents that result in Joule losses
                      and a time delay between the applied voltage and the
                      aperture field. User experiments impose stringent
                      requirements on beam operation to preserve the point of the
                      radiation source. To meet the demanding feedback
                      requirements, finite element simulations are needed to
                      understand the characteristics of the fast corrector magnet
                      and its environment. However, due to the low skin depths at
                      high frequencies and the laminated structure of the magnets'
                      yoke, conducting finite element simulations of the fast
                      correctors is computationally very demanding. Therefore, we
                      homogenize the laminated yoke which drastically reduces the
                      computational effort but still captures the eddy current
                      effects accurately. The homogenization technique reduces
                      simulation times from several hours to just a few minutes,
                      allowing us to conduct extensive studies of the power
                      losses, the field quality, and the integrated transfer
                      functions of the magnets.},
