Abstract: (1885 Views)
We present a new model for performance analysis of hyperbolic metamaterial with ultra-thin metal layer. Based on theoretical analysis, we have been modified Drude relation for metal layers with geometric size below ten nanometers. Then, the effect of this relation applied to transverse and perpendicular effective permittivity. Then, dispersion relation and transition and reflection relations coefficient for these structures are modified. The numerical calculation show, when we apply the effect of ultra-thin metal in HMM structure, the magnitude of effective permittivity is reduced about 45.28% in real part and 52.68% in imaginary part. These variations in effective permittivity limit the magnitude of transmission coefficients to 15%.
