| الوصف: | We designed a non-linear composite metamaterial made up of sandwiched fused silica glass with silver in an alternate manner with the magnitude of thickness is adjusted so that ε'=0 in the near infrared range., and the structure’s optical behaviour is theoretically studied. It shows a shift from negative to positive in the real component of dielectric permittivity as a function of wavelength. we also have studied the variation of ENZ wavelength with thickness of dielectric layer and plasma frequency. By using the Maxwell Garnett theory, we have calculated non-linear optical properties, and we find that as we increase the thickness of dielectric material the ENZ wavelength increases along with the increases in real part of non-linear susceptibility. A significant enhancement in nonlinear parameters has been also observed at ENZ wavelength due to the ENZ nature of the composite material. |
