In this work, we show theoretically how the trajectories of an optical beam propagating in a planar-homeotropic hybrid nematic crystal cell can be modified by applying a low frequency electric field perpendicular to the cell. We use a previously developed formalism for describing the propagation of a polarized beam through the cell. We include a low frequency electric energy for the calculation of the equilibrium orientational configurations of the director's field. The presence of the electric field gives rise to trajectories showing a nontrivial dependence of the beam's range and penetration length with the intensity of the applied electric field.
