Declares the epsS material property for Lithium niobate coefficient set (Ogi et al., 2002) with release value [["3.989e-10[F/m]","0[F/m]","0[F/m]"],["0[F/m]","3.989e-10[F/m]","0[F/m]"],["0[F/m]","0[F/m]","2.32e-10[F/m]"]].

The property remains tied to this material's declared sources, conditions, model assumptions, units, and shape metadata; it is not cross-spliced from another definition.
