In this paper, some generalizations of electromagnetic scattering problems by elementary shapes are presented. In particular, the aim of the paper is to provide solutions to the scattering problem by multiple objects with simple shapes, either in concentric configuration or arbitrarily distributed in the space. The vector harmonics, representing the fields, and their properties are applied in order to solve five different problems: the electromagnetic scattering by an infinitely long circular stratified cylinder, by a multilayered sphere, by an ensemble of parallel cylinders, by an ensemble of multi-spheres, and ultimately by a sphere embedded in a circular cylinder. Numerical results in particularly important configurations are shown.
本文给出了基本形状电磁散射问题的一些推广。特别地,本文旨在提供具有简单形状的多个物体散射问题的解决方案,这些物体可以是同心配置,也可以是在空间中任意分布。为了解决五个不同的问题,应用了表示场的矢量谐波及其性质:无限长圆形分层圆柱、多层球体、平行圆柱集合、多球体集合以及最终嵌入圆柱中的球体的电磁散射。展示了特别重要配置下的数值结果。
