Simple formulations including scattering interaction up to the second order are developed for thin dielectric disks and thin dielectric cylinders representing vegetation leaves and stems. In the iterative approach, Rayleigh-Gans approximation is used to calculate the internal electric field, or equivalently the induced polarization current, of the particles. To calculate the second-order scatter field, the exact near fields from all nearby particles are calculated numerically and used as the excitation for the second-order induced polarization current. Second-order polarization current at any given point within the scatterer is determined using the appropriate probability tensor.
