Abstract
A method of making an optical film for control of light includes positioning a first mixture on a substrate, wherein the first mixture includes a first plurality of magnetizable particles dispersed in a first resin, assembling the first plurality of magnetizable particles into a desired structure for the control of the light by rotating modulation of at least a first magnetic field relative to the first plurality of magnetizable particles, and vitrifying the first resin while the first plurality of magnetizable particles are in the desired structure.
