Résumé

A study of the self-healing property of weakly-diffractive vector beams radiated by a finite circular radiating aperture on an infinite ground plane is presented. The obstacle is a circular metallic disk, which is axially aligned and placed at a certain distance over the radiating aperture. Three different field distributions are considered as excitation for the aperture: the non-diffractive Bessel beam (BB), the Bessel-Gauss beam (BG), and the transverse electromagnetic mode (TEM) of a coaxial cable. The analysis is performed resorting to a spectral Green approach and to a Physical Optics (PO) framework. In all cases, a radially polarized beam is assumed. The results confirm the self-healing property of the non-diffracting beams. They also show the impact on the amplitude of the regenerated field due to the obstacle radius. The chosen approach is validated using a full-wave commercial software.
