Helmholtz-Galerkin Technique for the Analysis of the Diffraction from a Resistive-Filled Circular Hole in a Resistive Plane

In this paper, the analysis of the plane-wave diffraction from a resistive-filled circular hole in a resistive plane is formulated in terms of an infinite set of singular dual integral equations in the vector Hankel transform domain. To achieve an approximate solution of the problem, the integral equations are suitably discretized by means of the HelmholtzGalerkin technique, thus leading to fast-converging Fredholm second-kind matrix operator equations in $l^{2}$.
