Abstract

Leaf scatterers are a type of obstacle that is abundant in rural propagation en- vironments. These leaf scatterers interact with propagating radio waves which may affect the performance of wireless systems operating in such environments. In this paper, deciduous leaf scatterers are modelled as thin dielectric disks. The electromagnetic scattering from these disks at 2 GHz are modelled using the generalised Rayleigh-Gans (GRG) approximation as well as using a commercial method of moment (MoM) solver. The difference between the GRG and MoM results for the single scatterer case is evaluated using the spherical wave expansion of the scattered fields from both methods. An approximation of the scattered fields for the multiple scatterer scenario based on the superposition of the GRG scattered fields is presented and is compared to MoM results.
