一维Weierstrass分形粗糙表面光散射特性研究

The characteristic study of light scattering on 1-D weierstrass fractal rough surface

本文采用Weierstrass-Mandelbort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,利用基尔荷夫近似推导出Weierstrass-Mandelbort分形粗糙表面的光散射场的积分公式,数值计算并分析了表面散射光强的角分布特性。

This letter proposes a method for the generation of Weierstass - mandelbort fraetal surface, based on Helmholtz eqution, within the Kirehhoff approximation,we could compute the calculus formula of light scattering field on the Weierstrass - Mandelbort fractal surface, calculate numerically and analyze the angular distribution of the scattered intensity.
