[en] This paper deals with time-domain surface-impedance boundary conditions in computational magnetodynamics considering both magnetic-vector potential and magnetic-field formulation. Based on the resolution of the 1-D eddy-current problem in a semi-infinite slab, the massive conducting region is accounted for by choosing a number of exponentially decreasing trigonometric basis functions covering the relevant frequency range. Herein the method is elaborated for the magnetic-field formulation. Results for both formulations are compared and validated on a two-dimensional test case.
