Abstract
A multiband metamaterial operating in the 0 THz to 2 THz range was designed with two high refractive index values. The dimension of the slab of the metamaterial is 300 um by 300um and the thickness is 17.45 um. Twenty five resonant metallic structures were placed in the substrate material, with a gap of 1.2 um between each unit. Results show enhanced dielectric response as well as suppressed diamagnetic response at these frequencies, which exhibit high permittivity and high permeability. Two bands of high refractive index were observed in the FDTD simulation result.
