Abstract :
This paper proposes an original electromagnetic inverse procedure and numerical regularization for the return stroke current identification, from electric and magnetic field measurements in the area of the impact. The resulted evaluations prove to be in a very good agreement with the actual data, moreover the precision is considerably improved.
