Short summary
A new analytical method has been introduced to exactly solve the classical problem of electromagnetic diffraction by a slit. It is faster and easier to implement than the standard solution using Mathieu functions. Moreover, the paper contains a successful comparison of the scattered fields for an incident plane wave with that one obtained for an incident Gaussian beam which is easily modelled by a complex-source beam.
