Abstract

Diffraction of a two-dimensional electromagnetic beam wave by a thick slit pierced in a perfectly conducting screen is studied, based on Maxwell’s equations and their associated boundary conditions. The incident field is not a plane wave but a more-realistic beam. Special attention is devoted to the numerical aspect, which seems essential in such a study.
