We have analyzed total spin angular momentum of surface waves localized at a metasurface described within an effective conductivity approach. We show that hybrid TE-TM polarized surface waves propagating along the anisotropic metasurface provide unprecedented control over the spin angular momentum of light. The obtained results can be used in a number of photonic applications.
