Abstract
In this paper, the analysis of the electromagnetic scattering from a zero-thickness perfectly electrically conducting disk is carried out by means of the method of analytical preconditioning applied to an integral formulation in the vector Hankel transform domain. A complete set of orthogonal eigenfunctions of the static part of the integral operator reconstructing the physical behavior of the surface current density is used to discretize the integral equation. In this way, the obtained matrix equation, which is a Fredholm second-kind equation, is fast convergent. Numerical results are provided showing the efficiency of the proposed method.
