    Abstract

    A numerical method is presented which allows the calculation of the a.c. response of type II superconductors under quasi-static conditions for arbitrary jc (B,x), Ben (Ba) and Bex (Ba) relations. Flux distributions, induced voltage waveforms, hysteresis loops and a.c. losses have been calculated. Deviations between experimental results and earlier calculations with respect to a minimum in the a.c. losses are explained by taking into account the finite thickness of the sample and realistic Ben (Ba) and Bex (Ba) relations.
