摘要

本文采用二维归一化带限Weierstrass分形函数来模拟二维分形粗糙面

主要利用基尔霍夫近似研究了该粗糙面的电磁散射

给出了散射场、平均散射强度系数和散射强度方差的计算公式

通过理论分析和数值计算讨论了散射场与分维及粗糙面其他有关参量间的关系.

Abstract

In this paper

a normalized two-dimensional band-limited Weierstrass fractal function is presented for modeling the rough surface

and an analytic solution of the scattering field from two-dimensional band-limited Weierstrass fractal surface is derived based on Kirchhoff theory.The scattering field

the average scattering coefficient and the variance of scattering intensity are given to study the influence of fractal dimension and other related parameters on the scattering field by theoretical analysis and numerical calculations.
