Various embodiments set forth liquid crystal (LC) patterning control systems in which LCs are aligned using locally applied magnetic fields. The index of refraction experienced by light propagating through an anisotropic LC is dependent on orientation. As a result, a phase difference may be imparted to an optical beam that is passed through, or reflected from, an array of LCs whose orientations are controlled via locally applied magnetic fields. In some embodiments, the locally applied magnetic fields may be generated by driving currents through wires that intersect at micro or nanomagnetic particles or at magnetic domains, or by applying voltages to micro or nanocoils wrapped around high-permeability cores, among other things.
