We propose a semi-analytical scheme for investigating the electromagnetic beam scattering by a uniaxially anisotropic chiral object. The scattered and internal fields are expanded in terms of appropriate spherical vector wave functions, and the method of moments procedure is employed for determining the unknown expansion coefficients. Normalized differential scattering cross sections are evaluated for a uniaxially anisotropic chiral spheroid and circular cylinder of finite length, respectively illuminated by a Gaussian beam, Hermite-Gaussian beam and zero-order Bessel beam. The scattering properties are analyzed briefly.

我们提出了一种半解析方案,用于研究单轴各向异性手性物体的电磁束散射。根据适当的球面矢量波函数扩展了散射场和内部场,并采用矩量法确定未知的扩展系数。对分别由高斯光束,厄米-高斯光束和零阶贝塞尔光束照射的有限长度的单轴各向异性手性椭球体和圆柱体进行归一化微分散射截面的评估。简要分析散射特性。
