Claim Text:
1. A double-negative metamaterial, comprising a periodic array of single-resonator unit cells, each resonator comprising at least one inclusion in a dielectric structure wherein the at least one inclusion has a different permittivity than the dielectric structure material and wherein the at least one inclusion comprises at least one high-permittivity inclusion, thereby shifting the higher frequency, lowest-order electric resonance of the resonator to a lower frequency, and at least one low-permittivity inclusion, thereby shifting the lower frequency, lowest-order magnetic resonance of the resonator to a higher frequency such that the electric resonance and the magnetic resonance of the resonator are in alignment at an operating frequency, thereby providing a metamaterial having a negative index of refraction.
