Application of graphene as electromagnetic metamaterials in THz regime (0.1THz - 10 THz).
1, the terahertz modulator: In the external field, the graphene exhibits a high electrical resistance and induced magnetoresistive that can be used to change the light transmittance of terahertz graphene devices or reflectance, in order to achieve a modulation terahertz devices.
2,The tunable terahertz filter: it is similar to the working principle of the modulator, the transmittance of terahertz graphene filter can be adjusted, and the frequency range of the filter can also be adjusted.
3 THz waveguide: graphene conductivity and excellent properties make it two-dimensional natural choice terahertz waveguide material and, as the waveguide material, the reflectance can be adjusted.
4 THz polariser: graphene can be easily grown on a substrate of silicon or silicon carbide graphene array of narrowband light having anisotropy terahertz transmittance, so as terahertz polariser. to use.
5 THz beam splitter: multi-graphene can be used as a terahertz optical splitter, and the transmitted light and the sub-light-emission can be adjusted by the ratio of the number of layers of graphene, and the size of the applied electric field, so that a continuously adjustable THz beam splitter is possible
Mr. Kittipong Tripetch, graphene is preferred for designing the ultra low power operating transistors. Graphene has lot of advantages than silicon. You can try graphene based transparent conductors/transistors. good luck.
