Abstract - The accuracy of the hybrid method is validated by showing that the computed solutions of three trees are in good agreement with those solved from FEKO. Next the hybrid method is used for Monte Carlo simulations of forest stands with up to 30 trees. The dependences of the solutions on tree heights and tree densities are illustrated. The results show that the full-wave based transmissivities are much larger than those obtained from the radiative transfer equation (RTE) model.
