摘要
采用Weierstrass分形函数模拟实际粗糙表面,从简谐光波满足的亥姆荷兹方程出发,利用基尔霍夫近似推导出一维Weierstrass分形粗糙表面的光散射场的积分公式,考虑遮蔽效应后数值计算并分析了表面散射光强的角分布特性。
A method for the generation of Weierstrass fractal surface is presented, based on Helmholtz equation, with the Kirchhoff approximation, the calculus formula of light scattered field on the 1-D Weierstrass fractal suface is deduced. In view to shadow effect, the characteristic of angular distribution of the scattered intensity is analyzed.
