摘      要：Recently,it was predicted that extraordinary light waves in hyperbolic metamaterials may exhibit two-time physics *** report experimental observation of this effect via investigation of gravity-like nonlinear optics of iron/cobalt-based ferrofluid hyperbolic *** addition to conventional temporal coordinates,the spatial coordinate oriented along the optical axis of the metamaterial also exhibits timelike character,which leads to very unusual two-time physics behavior in these systems on small scales.
