Ultrabroadband Unnaturally High Effective Refractive Index Metamaterials in the Terahertz Region
We demonstrate that an ultrabroadband, extremely high index of refraction can be realized from the thin window-type terahertz metamaterials composed of strongly multilayer coupled unit cells. By drastically increasing the effective permittivity by means of intense capacitive coupling and reducing th...
