A versatile scattering model for deciduous leaves

A versatile, multi-frequency scattering model is developed for deciduous leaves. The model gains its versatility from estimating the field inside the leaves, which are represented by elliptic discs, through employing a technique bridging the generalized Rayleigh-Gans (GRG) and the physical optics (PO) approximations. Analytic and numerical results are presented to illustrate the model versatility.
