Résumé

In this paper we propose a hybrid method for evaluating the electromagnetic field radiated by lightning taking into
account the effect of the conductivity of the soil. The proposed method is the combination of the images method and
finite difference time-domain (FDTD) method. The magnetic field is obtained by the use of the images theory and
the electric field is solved with using FDTD method. We calculate first, the electromagnetic field with supposing the
ground as a perfect conductor and secondly we introduce the effect of the conductivity of the soil by the use of
approximations formula.
