Abstract: A device is described for switching the direction of visible and near-visible electromagnetic radiation traveling in the plane of a thin film of magnetic material. The invention is based on the interaction of electromagnetic radiation with patterned regions (such as a diffraction grating or a waveguiding strip) whose coercivity is different from that of the area surrounding the regions.
