Query: Steering visible Dyakonov surface waves at the hyperbolic metasurface   Dyakonov surface wave existing at the interface with anisotropy offers a
promising way of guiding light in two-dimension with almost no loss. However,
predicted decades ago, the experimental demonstration of the Dyakonov surface
wave seems always challenging for the weak anisotropic indices from the natural
materials. Here we experimentally demonstrated a Dyakonov surface wave mode
propagating in a hyperbolic metasurface at the visible frequency. Dyakonov
surface waves at the two surfaces of the metasurface can be supported
simultaneously by the hyperbolic anisotropy and form a Dyakonov typed mode with
low loss and a large allowed angle band. A detailed theoretical analysis and
numerical simulations prove that the electric field of such a surface wave mode
shows transverse spin, whose direction is determined by the orientations of the
hyperbolic anisotropy and surface normal, based on which we experimentally
observed the photonic spin Hall effect of the surface wave mode in our
metasurface.
