Abstract

The electromagnetic scattering from the rough surface of layered medium with circular polarized wave incidence is studied, the formulae of the scattering coefficient for different polarization is derived using the small perturbation method. A Gaussian rough surface is presented for describing the natural surface of layered medium, the formulae of the bistatic scattering coefficient is deduced. The angular distribution of the bistatic scattering coefficient that the incident wave and scattering wave are right-handed circular polarization are obtained by numerical implementation, the influence of the permittivity of substrate medium, the permittivity and the mean layer thickness of intermediate medium, the roughness surface parameters and the frequency of the incident wave on the bistatic scattering coefficient is discussed. The numerical results show that the influence of the permittivity of substrate medium, the permittivity and the mean layer thickness of intermediate medium, the roughness surface parameters and the frequency of the incident wave on the bistatic scattering coefficient is very complex.

圆极化波入射层状介质高斯粗糙表面电磁散射研究

研究了圆极化波入射层状介质粗糙表面的电磁散射，利用小摄动法推导了不同极化下的散射系数公式。提出了一种描述层状介质自然表面的高斯粗糙表面，推导了双稳态散射系数的计算公式。通过数值实现得到了入射波和散射波均为右旋圆偏振的双基地散射系数的角分布，讨论了基片介质的介电常数、中间介质的介电常数和平均层厚、表面粗糙度参数和入射波频率对双基地散射系数的影响。数值结果表明，衬底介质的介电常数、中间介质的介电常数和平均层厚、表面粗糙度参数和入射波频率对双基地散射系数的影响是非常复杂的。
