Abstract

An effective numerical modeling based on Method of Moment (MoM) and equivalent material technique is proposed to predict the radio wave propagation over forest canopies. In contrast to conventional approach where a planar interface was assumed between the free space and forest canopy, the MoM based on a forward-backward method allows one to model the interface in terms of rough surface in a more realistic fashion. Numerical examples validate the modeling techniques
