• Resumen

  • The skin effect in a rectangular bus‐bar is first computed by a direct method of three‐dimensional discretisation. A superior method based upon Huygens’ principle is then presented; discretisation only of the surface is performed; the eddy currents are regarded as propagation from surface elements through a medium, whose attentuation is determined by the conductivity. Results are compared and the application of Huygens' principle is justified by savings in time and storage space.
