Abstract

We report on the role of the coupling of the modes of Mie resonances in an all-dielectric metamaterial so as to achieve negative index at terahertz frequencies. We studied this role according to the lattice spacing and according to the frequency overlapping of the modes of resonance. We show that negative effective index requires sufficiently high mode coupling.
