The scattering of electromagnetic radiation by apertures. 5. Surface current, tangential aperture electric field, and back-scattering cross-section for the axially slotted cylinder at normal, symmetric incidence

Abstract : The report considers the thin-walled perfectly conducting, axially slotted, infinite circular cylinder, and the infinite cylindrical strip. For the case of incidence simultaneously normal to the cylinder axis and parallel to the symmetry plane bisecting the infinite axial slot, it presents the analytical formulation of the integral equations for the surface current on the conductor and also those for the tangential component of the electric field over the slot. The incident radiation is assumed merely for simplicity to be monochromatic, plane, and linearly polarized parallel to the cylinder axis.
