Abstract :
Herein, we suggest a fast approximate 3D numerical model for the interaction of an electromagnetic wave with a forest. Contrarily to other such approximate models found in the literature, this model accounts for the reciprocity of the double bounce scattering mechanism observed in particular configurations. This reciprocity is enforced at the scattering matrix level. The model is tested and compared to a rigorous model based upon an integral representation of the fields.
