Abstract
The problem of wave propagation in forest is revisited in particular, the effect of the non-planar interface between the air and the canopy on lateral waves is examined. An analytical formulation is obtained for the mean field when both the transmitter and receiver are within the foliage. This formulation is based on the distorted Born approximation and is shown that compared to a planar interface, the field of a dipole in a canopy with rough interface is significantly reduced.
