摘要: Abstract A method for the calculation of magnetic field dynamics and AC losses in superconductors with smooth current–voltage characteristics is described. It based on an integral equation current density, recently used by Brandt relaxation. Brandt's generalized to include arbitrary external fields transport currents. One benefits formulation that no boundary conditions `at infinity' are required, thus restricting region conductor cross section. The applied superconducting tapes oblique fields. further extension theory shown be applicable coupling twisted multifilamentary superconductors.
