| Popis: | In this paper, we propose a metamaterial film bounded by a nonlinear cover and a dielectric substrate as a THz wave sensor. The dispersion characteristics and magnetic field profiles have been derived, computed and analyzed. Confinement of the light waves was found to increase with both nonlinearity and frequency. We believe our results can be used to design novel tunable future sensors. |
