Summary:
We demonstrate extremely high indices of refraction from large-area, freestanding, flexible terahertz metamaterials. The highest index of refraction of 33.22 is obtained from a multilayer metamaterial at a frequency of 0.851 THz. In addition, we fabricated polarization-independent high index metamaterials composed of hexagonal/square metallic ring and demonstrated polarizationinsensitive effective refractive indices.
