The optical properties of non-ideal completely ionized plasma are discussed from the perspective of the kinetic theory approach. It is demonstrated that a physically motivated modification of the Coulomb logarithm, originally proposed in the context of ion-particle scattering in dusty plasma, allows us to improve the theoretical description of the dynamical conductivity and hence of the optical properties of plasma in the moderately non-ideal regime. The obtained analytical results for the refractive index, reduced absorption and reflection coefficients can be straightforwardly implemented for practical calculations. The comparison between experimental and theoretical results for the reflectivity is performed and discussed in some detail.

从动力学理论方法的角度讨论了非理想完全电离等离子体的光学性质。结果表明，最初在尘埃等离子体中离子粒子散射的背景下提出的库仑对数的物理驱动修改，使我们能够改进动态电导率的理论描述，从而改进中等非等离子体中等离子体的光学性质的理论描述。 -理想的制度。所获得的折射率、降低的吸收和反射系数的分析结果可以直接用于实际计算。对反射率的实验结果和理论结果进行了比较，并进行了一些详细的讨论。
