Popis: High-order harmonic generation (HHG) has been demonstrated as a successful technique to produce extreme ultraviolet (XUV) coherent light with controlled spin, or polarization, (SAM) and orbital angular momentum (OAM). For gaseous targets, the harmonic composition rules follow from the independent and simultaneous conservation of each type of angular momenta [1] . However, light beams can exchange SAM and OAM at the nanoscale when propagating through inhomogeneous media [2] . Although spin-orbit optical interactions are often regarded to generate negligible effects, several fundamental studies have recently demonstrated their relevance when working at the nanoscale, with potential applications for manipulating small particles and controlling light propagation [3] .
