Paper Abstract

For the first time it can be shown, experimentally and theoretically, that the field of plane wave, which diffracted on the perfectly conducted half plane (Sommerfield's solution), is presented as a superposition of the half amplitude source wave and wave, which contains edge dislocation that is formed on the screen border and described by the complex Fresnel integral. These two waves are real waves, unlike traditional representation as sum geometric and boundary waves, and as we have shown, can be split and investigated experimentally. On basis of this new representation the problem of diffraction arbitrary beam on the perfectly conducted half plane was solved. It was shown (theoretically and experimentally) that a diffracted beam is presented as a sum of the source beam half amplitude and a beam contains edge dislocation that is caused by the border of the screen.
