Light paths in a ferronematic cell.
The control of the light trajectories in a liquid crystal is studied through a theoretical model based in the variation of the molecular orientation of a ferronematic material. In this model, the director field is mapped into a Riemannian space where the light paths are obtained numerically through the calculation of the geodesics for the effective geometry perceived by light.
