EM Scattering from a Dielectric Circular Clinder of Finite Length

A new iterative technique based on the T-matrix approach for the electromagnetic scattering by dielectric cylindrical objects is proposed and the boundary conditions are also carefully treated in this paper. The validity of the proposed method is demonstrated through agreement between theoretical predictions and numerical simulations as well as measurements for scattering from circular cylinders with finite length. The results clearly demonstrate that the new iterative technique can extend regular T-matrix approach to solve rod cases with large aspect ratio.
