Diffraction of Electromagnetic Waves At Plane Apertures: a Different Approach

Abstract

An approach based on integral equations, different from the conventional ones, was previously applied [1] to the diffraction of scalar waves at plane apertures. The same technique generalized to vector integral equations with tensor Green's functions solutions of Maxwell's equations, is used to deal with the diffraction of electromagnetic plane waves. Explicit formulae are given for the electric field with an application to the diffraction by a slit.
