    Abstract

    A new concept to realize negative refractive index in non-resonance spectrum using chiral metamaterial is proposed. A low-index metamaterial is added to diminish the effective refractive index of the combined structure. Simulation and material parameter retrieval procedures are carried out to determine material performances. Results show evidence of negative refractive index and strong optical activity in the new chiral metamaterial.
