  • Tunable compliant optical metamaterial structures
    Patent number: 8921789
    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.
