Cutoff frequency in metamaterials photonic crystals within Terahertz frequencies

By employing the characteristics matrix method, we have investigated the transmission properties of one-dimensional dielectric semiconductor metamaterial photonic crystals (PC) at Terahertz (THz) range theoretically. The numerical results show the appearance of cutoff frequency within THz range. Furthermore, the thicknesses of the constituents materials and the filling factor have a significant effect on the cutoff frequency. The proposed structure may be useful in many applications, particularly in THz frequency regions.
