Abstract: A method for creating metadevices includes receiving, at a computing device, one or more boundary conditions for a metadevice. The method also includes processing, with an inverse-design algorithm stored in a memory of the computing device, the one or more boundary conditions to generate a metadevice structure design that satisfies the one or more boundary conditions. The method also includes converting, by a processor of the computing device, the metadevice structure design into a file that is compatible with an additive manufacturing device. The method further includes providing the file of the metadevice structure design to the additive manufacturing device.

Abstract: Methods of fabricating an object via direct laser lithography are provided. In embodiments, such a method comprises illuminating, via an optical fiber having an end facet and a metalens directly on the end facet, a location within a photosensitive composition from which an object is to be fabricated with light, thereby inducing a multiphoton process within the photosensitive composition to generate a region of the object; and repeating the illuminating step one or more additional times at one or more additional locations to generate one or more additional regions of the object.

Abstract: A tunable metamaterial structure, comprises a flexible substrate capable of being strained, a metamaterial pattern on a surface of the flexible substrate, and a metal layer on the metamaterial pattern. The flexible substrate of the tunable metamaterial structure is a strained and relaxed substrate which has been strained to a degree sufficient to register a resonant response upon relaxation that is shifted relative to the resonant response of the flexible substrate prior to being strained. The application of strain to the flexible substrate of the metamaterial structure enables tuning of the resonant frequency.
