Near field analysis of a perfectly conducting slotted elliptic cylinder

Abstract

Near-field analysis of a perfectly conducting slotted cylinder excited by an electric line source or a z-polarized incident wave is considered. The problem is reduced to an integral equation in terms of the aperture field. The solution of the integral equation is carried out by expressing the aperture field in terms of a Fourier series expansion with unknown coefficients. Then Galerkin's technique is used to solve for the unknown aperture field coefficients.<>
