摘要：

We report on the THz harmonic generation in a graphene/metamaterial device by using ultrafast table top powerful THz-TDS systems. A complex nonlinear transmission spectra, which includes a peak at the third harmonic signal is detected on top of the main resonant features at 0.65 THz, for E-field pulses in the range 1-30 kV/cm. Whilst these results are consistent with acquainted literature, they offer a novel perspective for the exploitation of graphene nonlinearity in integrated devices.
