The present invention provides a novel near infrared (NIR) metamaterial device that can be transformed into various shapes by bending the flexible substrate, wherein said metamaterial device is tunable via physical manipulation of its flexible substrate with no requirement of changing the material composition of the substrate.
Most of the current optical metamaterial nanostructures are fabricated on rigid substrates, and the conventional processes are very slow if the substrate size is limited. This invention introduces a laser interference lithography technique for the fabrication of flexible metamaterial or plasmonic nanostructure in a large area, which has potential applications such as imaging and environmental sensors.
