Extraordinary Young’s interference is an anomalous phenomenon observed at metallic surface in 2004. The shrinkage of slit size into deep subwavelength scale introduces many novel effects that cannot be described by classic interference theory. In this paper, the Young’s interference excited by subwavelength slits is investigated via rigorous Maxwell’s equations. We reveal a universal spin–orbit interaction mechanism associated with the catenary optical fields in 2D isotropic metal-dielectric…
