Abstract

The field of transformation optics shows that media containing gradients in optical properties are equivalent to curved geometries of spacetime for the propagation of light. Conformal transformation optics — a particular variant of this feature — can be used to design devices with novel functionalities from inhomogeneous, isotropic dielectric media.
