- Optical_metric abstract "The Optical Metric was defined by German theoretical physicist Walter Gordon in 1923 to study the geometrical optics in curved space-time filled with moving dielectric materials. Let ua be the normalized (covariant) 4-velocity of the arbitrarily-moving dielectric medium filling the space-time, and assume that the fluid’s electromagnetic properties are linear, isotropic, transparent, nondispersive, and can be summarized by two scalar functions: a dielectric permittivity ε and a magnetic permeability μ. Then optical metric tensor is defined as ĝab = gab + (1 - 1/εμ) uaub ,where gab is the physical metric tensor. The inverse (contravariant) optical metric tensor is ĝab = gab + (1 - εμ) uaub ,where ua is the contravariant 4-velocity of the moving fluid.Note that the traditional refractive index is defined as n(x) ≡ √εμ .".
