Abstract

In this work, we used effective medium approximation and the Drude-Lorentz model with one oscillator for transparent conducting oxide optical permittivity to design multilayered stacks of transparent conducting oxides and dielectrics. The influence of the material parameters for the multilayered metamaterial on nonlinearity and higher-order dispersion are presented. The finite-difference time domain (FDTD) numerical simulations are used to investigate the pulse propagation at the ENZ spectral point. The results based on a full wave analysis study performed using FDTD numerical algorithm show a dramatic pulse shaping for femtosecond pulses at the epsilon-near-zero spectral point.
