Spin-orbit coupling influences topology of evanescent waves and vector beams propagation. In evanescent fields, the coupling is mediated by the transverse spin and results in complex topological field structures analogous to prototypical condensed matter phenomena, such as quantum spin-Hall effect, skyrmions, merons, and others. These topological beams also provide nontrivial magneto-optical interactions. At the same time, the interaction of propagating vector beams and metamaterials in many cases strongly depends on the longitudinal field of the beam and can be used for controlling the beam polarisation and modal structure. In this talk, we will discuss spin-orbit coupling in guided waves and complex vector beams, both carrying longitudinal fields, their topological manifestations, interaction with anisotropic and epsilon-near-zero metamaterials, and their applications.
