Electromagnetic scattering from a thin resistive disk: A new analytically regularizing approach

In this paper a new analytically regularizing procedure for the analysis of the electromagnetic scattering from a thin resistive disk is shown. After formulating the problem in terms of an integral equation in the Hankel transform domain, the surface curl-free and divergence-free contributions of the surface current density are assumed as new unknowns. A second-kind Fredholm infinite matrixoperator equation is obtained by means of Galerkin method with expansion functions reconstructing the physical behavior of the unknowns with closed-form spectral domain counterparts. Moreover, the matrix coefficients are efficiently evaluated by means of analytical asymptotic acceleration technique.
