Patent ID: 10593873

Abstract:
A device for switchably influencing electromagnetic radiation includes a phase change material and an optically responsive structure. The phase change material is switchable between at least a first state and a second state. The first state and the second state have different electrical and/or magnetic properties. The optically responsive structure is in contact with the phase change material and has at least a first nanostructure and a second nanostructure. The first nanostructure is being different from the second nanostructure. The first nanostructure is optically responsive at a predetermined electromagnetic wavelength when the phase change material is in its first state, and non-responsive at the predetermined wavelength when the phase change material is in its second state. The second nanostructure is optically responsive at the predetermined electromagnetic wavelength when the phase change material is in its second state, and non-responsive at the predetermined wavelength when the phase change material is in its first state.
