摘要
采用小斜率近似方法研究了电磁波掠入射时导体粗糙面的电磁散射问题,同时将其结果与考虑遮蔽效应的基尔霍夫近似和有关实验结果作了比较,表明小斜率近似在整个入射角范围内包括散射角较大时与实际测量结果都较为吻合.
The electromagnetic scattering form the rough surface using the small slope approximation is investigated, The results by the small slope approximation are also compared with that of the Kir.chhoff approximation with shadowing effect considered and the experimental data. It is found that the small slope approximation is more accurate for the whole incident angle and the numerical results also show good agreement with the experimental data for the large scattering angle.
