Abstract
The plasmonic mode in graphene metamaterial provides a new approach to
manipulate terahertz (THz) waves. Graphene-based split ring resonator (SRR)
metamaterial is proposed with the capacity for modulating transmitted THz
waves under normal and oblique incidence. Here, we theoretically demonstrate
that the resonant strength of the dipolar mode can be significantly enhanced
by enlarging the arm-width of the SRR and by stacking graphene layers. The
principal mechanism of light–matter interaction in graphene metamaterial
provides a dynamical modulation based on the controllable graphene Fermi
level. This graphene-based design paves the way for a myriad of important THz
applications, such as optical modulators, absorbers, polarizers,
etc.
