Abstract: (4774 Views)
We consider a plane metamaterial with unit cells composed of short wire pairs and continuous wires. We investigate the effect of the value of the dielectric constant of the dielectric layer between short wires on the effective refractive index of the structure. By increasing the value of the dielectric constant, the effective refractive index of the structure changes from negative values to positive values. Inspired by this phenomenon, we can construct a metamaterial that its effective refractive index changes sign as the intensity of the incident light is increased.
