The interaction of a stratified cylinder with an elliptically inhomogeneous plane wave is introduced and also determined through a rigorous theoretical approach. The scattered electromagnetic field by a multilayered cylinder is investigated through an application of the generalized Vector Cylinder Harmonics (VCH) expansion. The exact mathematical model to represent this scenario considers the so-called complex-angle formalism reaching a superposition of Vectorial Cylindrical-Harmonics and the T-matrix formulation to contemplate the multi-scattering process between the cylinders. The validation of the procedure was accomplished with a comparison between the numerical results obtained with the Finite Element Method (FEM) in Comsol Multiphysics environment and a homemade Matlab code.

椭圆非均匀平面波与多层圆柱体之间的电磁散射

引入了分层圆柱体与椭圆不均匀平面波的相互作用，并通过严格的理论方法确定。通过应用广义矢量圆柱谐波 (VCH) 展开来研究多层圆柱的散射电磁场。表示这种情况的确切数学模型考虑了所谓的复角形式主义，达到了矢量圆柱谐波和 T 矩阵公式的叠加，以考虑圆柱之间的多重散射过程。通过在 Comsol Multiphysics 环境中使用有限元方法 (FEM) 获得的数值结果与自制的 Matlab 代码进行比较，完成了该程序的验证。
