Performances of Non-line-of-sight Ultraviolet Multi-Scatter Propagation for Noncoplanar Geometries

摘要：

　　A multi-scatter propagation model based on Monte Carlo method is presented.This model can be applied to all the geometries,including coplanar or noncoplanar scenario.The mathematical description of this model is deduced.We obtain the spatial positions of photon with three Cartesian coordinates after each propagation step and the received judgment conditions.Employing a photon tracing technique,Monte Carlo simulation is performed to investigate the signal impulse response and the path loss.The results indicate that,when the off-axis angle increases,the amplitude of the impulse response decreases,while the path loss increases.In addition,it is observed that the pulse width increases with the off-axis angle.
