    Abstract

    The puzzle of the effect of surface coupling in anisotropic media was solved by studying the surface modes of WS2 nanostructures with different geometries. Beyond the isotropic case, it was shown that the surface coupling in an anisotropic nano-object results in the existence of symmetric (tangential) and antisymmetric (radial) modes, even in real solids.
