1. An apparatus, which interacts with incident electromagnetic energy, the apparatus comprising:

  • a plurality of coupled closed-loop resonators distributed in a region,wherein each resonator has a resonant spectral response characterized by a quality factor Q (ω

    c), where ω

    is frequency, and ω

    c is a resonance line center frequency, and wherein positions and orientations of the resonators are distributed in the region in a selected spatial arrangement so that the apparatus collectively exhibits a particular effective refractive index n (ω

    ) to incident electromagnetic energy.
