摘要: In this paper we present a finite element model using the commercial COMSOL® software package for calculating ac loss in bifilar stacks of high temperature superconducting tape. model, current-voltage relationship characterizing properties is assumed to follow power law. The calculations were performed infinite with different values layer-to-layer separation D. With appropriate settings boundary conditions, numerical results agree well analytical data obtained from recently proposed [J. R. Clem, Phys. Rev. B 77, 134506 (2008)]. approach was also used investigate end effects stack answer following question: how many layers away are required before environment given layer identical that an stack? We find question depends strongly on value Based study, in...
