In this paper, a regularized full-wave analysis of electromagnetic scattering from a finite-length closed perfect electric conducting circular cylinder is presented. By exploiting the azimuthal symmetry of the problem, the classical electric field integral equation is reduced to an infinite set of systems of one-dimensional integral equations in the spectral domain and solved by applying the Galerkin method with expansion functions reconstructing the physical behaviour of the unknown induced surface current density. In this way, regularization and quick convergence are achieved. Comparisons with the results in the literature and the ones obtained by means of commercial software CST Microwave Studio Suite are presented, showing the effectiveness of the proposed method.This article is part of the theme issue 'Analytically grounded full-wave methods for advances in computational electromagnetics'.

Gauss's Law: Cylindrical Symmetry
Electric Field of a Charged Disk
The system's symmetry is in the cylindrical directions across the plane of the charge. As a result, the electric fields created by various surface charge elements nullify each other in the direction parallel to the surface. Thereby, the resulting electric field is perpendicular to the plane. Since the disk is...
