Calculation of permittivity tensors for invisibility devices by effective medium approach in general relativity [PDF]
J.Mod.Opt.58:700-710,2011, 2010 Permittivity tensors of arbitrary shaped invisibility devices are obtained using effective medium approach in general relativity. As special cases, analytical expressions for the permittivity tensors of invisibility cloaks for the elliptic cylinder, prolate spheroid, and the confocal paraboloid geometry are derived. In the case of elliptic cylinder, we
