Abstract:
We study the propagation of electromagnetic waves through a slab of graphene
metamaterial composed of
the layers of graphene separated by dielectric slabs. Starting from the kinetic expression
for two-dimensional
electric current in graphene, we derive a novel equation describing the nonlinear
propagation of THz
electromagnetic pulses through the layered graphene-dielectric structure in the presence
of losses
and nonlinearities. We demonstrate strong nonlinearity-induced reshaping of transmitted
and reflected
THz pulses through the interaction with the thin multilayer graphene metamaterial
structure.
