THz wave interaction with planar structures consisting of multilayer graphene sheets and bianisotropic slabs

An improved spectral-domain exponential matrix technique is proposed for investigating on the interaction of a THz wave with planar structures consisting of multilayer graphene sheets and bianisotropic slabs. Hybrid effects of different parameters, such as THz wave incident direction, its frequency and polarization, chemical potentials of the graphene sheets and constitutive tensors of the bianisotropic media, on the co- and cross-polarized reflection and transmission coefficients are characterized numerically, with their bandpass properties captured and compared. It is shown that there are more freedoms provided by layered graphene sheets and bianisotropic media at the same time, which can be exploited for effectively controlling the THz wave propagation.
