Scattering from a grounded chiral slab with rough interface is studied using perturbation theory. A system of equations for zeroth and higher order solution is written, which can be solved to get co and cross polarized scattered and transmitted field components. The zeroth-order coefficients provide the results for the flat case, while the higher order coefficients provide the solution with perturbation involved. Upon substituting the value of chirality of the medium to zero, we get the results for the dielectric slab to highlight the effect of chirality. Moreover, the parameters related to sinusoidal and Gaussian rough surfaces such as period and correlation length are changed to check their effects on the scattering pattern.

使用微扰理论从具有粗糙界面的接地手征板散射

使用微扰理论研究了具有粗糙界面的接地手征板的散射。编写了零阶和更高阶解的方程组，可以求解该方程组以获得同偏振和交叉偏振的散射和透射场分量。零阶系数提供平坦情况的结果，而高阶系数提供涉及扰动的解决方案。将介质的手性值代入零后，我们得到了电介质板的结果，以突出手性的影响。此外，改变与正弦和高斯粗糙表面相关的参数，例如周期和相关长度，以检查它们对散射模式的影响。
