Simulation of self-healing of polarization singularities

The generation and propagation of polarization singularities have been researched for years. In this article, we explored self-healing of polarization singularity generated from Bessel beams when encountering obstacles during propagation. The topological structure can be reconstructed due to the self-healing of Bessel beams, and we found that the reconstruction of the topological structure is much faster than the healing of the broken amplitudes.
