Investigation of self-reconstruction in polarization singularity lattice
On demand | Presented live 14 April 2026 
Abstract
This study investigates the self-reconstruction behavior of a polarization singularity lattice field when partially obstructed. Numerical simulations demonstrate that the lattice exhibits robust self-healing properties during propagation. This phenomenon is driven by the non-zero net transverse component of the beam’s Poynting vector. These findings suggest that such singular beams hold significant potential for applications in high-resolution microscopy and optical particle manipulation.
