We present a systematic theoretical study of current profiles, magnetic field lines, and hysteresis ac loss in linearly arranged arrays of rectangular superconducting strips subjected to a transport current. Results are obtained by means of numerical calculations assuming the critical-state model with a constant critical current density. Because finite filament thickness and magnetic coupling effects are considered, we can provide some useful hints as to how to arrange the filaments in order to reduce the ac loss in actual superconducting tapes. © 2005 The American Physical Society.
