AC losses in superconductor strips assembled face-to-face are numerically evaluated by means of a finite element method. The external magnetic field is applied perpendicular to their flat face. It is also assumed that the superconductor strips have the voltage-current characteristics represented by the critical state model with constant critical current density. The influences of the number of strips and the gap length between strips on the losses are quantitatively discussed as compared with the conventional theoretical expressions for some special cases in order to understand only the geometrical effects on the perpendicular-field losses in actual assembled conductors with the finite numbers of Y-based superconducting tapes.
