In this article, we introduce a Faraday modulator based on graphene, gyroelectric (InSb), SiO2, and Si materials at 0.35 THz, considered as a band of the atmospheric window promising for the future wireless communications. The maximum value of Faraday rotation, transmission and depth of modulation are obtained at 0.35 THz for low static magnetic field B as 45 deg, 80%, and 100%, respectively. The THz signal transmission can be modified from 0 to 80% by varying applied static magnetic fields. This design opens up a new way for ultrathin magneto-optical nanophotonic devices to realize polarization modulators with high transmittance in the THz band.
