Abstract

We demonstrate numerically that one-dimensional metamaterials with a gain medium can exhibit a near-unity-refractive-index for TE-modes, which resembles the effect of electromagnetically induced transparency. Our results are further supported by rigorous coupled wave analysis simulations. Additionally, we analyze the behavior of the modal gain and derive an approximate analytical solution of the dispersion equation that is superior to earlier solutions. Finally, a generalization to the case of ultralow refractive index has been considered.
