主　　题：metamaterial spin orbital coupling surface wave 

摘      要：We discover a new kind of surface wave on biaxial hyperbolic metamaterial,which,in the k-space,connects the two diabolical points(or conical singularities)of the equifrequency ***,the propagation of such surface wave is found to be sensitive to the refractive index of the surrounding dielectric medium,showing a convex,concave or flat phase front when the refractive index is ***,the surface wave shows an elliptically polarized state,in which helicity is dependent on the propagation *** feature can be utilized for the spin-controllable excitation of surface waves,opening a gateway towards integrated photonic circuits with reconfigurable functionalities.
