摘要：
The finite element method of Monte Carlo simulations of random rough surface scattering is extended to plane and tapered wave scattering from random metallic surfaces at optical frequencies. The backscattering enhancement associated with these rough surfaces is studied for both TE and TM incident waves. Numerical results of the finite element method are presented and compared with those of the tapered wave integral equation method. In all the cases considered, both the TE and TM incident waves show backscattering enhancement. The lossy surfaces scatter more power for TE incident waves than those of TM due to the TM surface waves. No TE surface wave is supported by rough surfaces simulated in this paper.
