Tunable window system for a vehicle

At least one non-transitory computer readable storage medium comprising a set of instructions which, when executed by a processor, cause the processor to:

• receive a signal from a photosensor indicative of a condition of incoming light to a vehicle;
• determine a change in a view for a window assembly based on the received photosensor signal,
• wherein the window assembly comprises a tunable optical metamaterial deployed on a surface of a window, the tunable optical metamaterial including a transparent electroactive substrate having disposed thereon an optically active particle array, the optically active particle array including resonators having elongated members arranged in two or more orientations;
• and
• control a voltage applied to the substrate to selectively expand or contract the substrate within a plane substantially parallel to the window surface and in a manner to adjust the view for the window assembly according to the determined view change, wherein the optically active particle array is optically responsive to the selective expansion or contraction of the substrate.
