    "abstract": "In this paper, we numerically demonstrate a near-infrared negative-index\nmetamaterial (NIM) slab consisting of multiple layers of perforated\nmetal-dielectric stacks and exhibiting low imaginary part of index over the\nwavelength of negative refraction. The effective index is obtained using two\ndifferent numerical methods and found to be consistent. Backward phase\npropagation is verified by calculation of fields inside the metamaterial. These\nresults point to a new design of low loss thick metamaterial at optical\nfrequencies.",
