A graphene-based metamaterial for THz plasmon induced transparency (PIT) is presented
and numerically studied in this paper, which consists of two horizontal graphene strips
attached to a continuous vertical wire separately. The calculated surface current distributions
demonstrate that the distinct PIT window results from the near-field coupling of two bright
modes. To explore the physical mechanism of PIT effect, we employ the coupled Lorentz
oscillator model. The transmission spectra obtained with this model fits well with the …
