Abstract:
A method and apparatus of fabrication of a multilayer flexible metamaterial can be fabricated using flip chip transfer (FCT) technique. This technique is different from other similar techniques such as metal lift off process, which fabricates the nanostructures directly onto the flexible substrate or nanometer printing technique. It is a solution-free FCT technique using double-side optical adhesive as the intermediate transfer layer and a tri-layer metamaterial nanostructures on a rigid substrate can be transferred onto adhesive first. Another embodiment of the present invention is the fabrication method and apparatus that allows the transfer of the metamaterial from a rigid substrate such as glass, quartz and metals onto a flexible substrate such as plastic or polymer film. Thus, a flexible metamaterial can be fabricated independent of the original substrate used.
