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.

In this contribution, a fast iterative method to solve for the fields scattered by thin layers of particles is presented. The particles are randomly positioned within the layer and are characterized by means of their T -matrix. The memory complexity of the problem is reduced by dividing the layer into uniform cells. Different preconditioning techniques are applied to yield an iterative solution. The speed and the memory requirements of the presented algorithm are compared to a direct calculation approach. As an example, the scattered fields of up to 6000 dielectric spheres that are excited with a gaussian beam are calculated. [ABSTRACT FROM AUTHOR]
