Abstract

The problem of nonstationary diffraction of a monopolar TM-polarized electromagnetic pulse with a flat front on a thin slit in a perfectly conducting screen is considered. Using computational experiment methods, it has been shown that if the slit width is much smaller than the spatial length of the pulse, then a field is formed behind the screen in the form of a cylindrical monopolar pulse, i. e. there is a transformation of the shape of the incident field front without changing its character (monopolarity).
