Abstract: (394 Views)
In this paper, the Faraday effect in a Graphene/SiO2/Ta2O5 layered structure under applying an external magnetic field, and a pump light of a Helium-Neon laser with a wavelength of 632.8 nm is investigated in the THz frequency region. Our results show that, as the magnetic field strength increases, the maximum Faraday rotation frequency shifts to the higher frequencies, and at the same time, the value of the maximum Faraday rotation angle increases. Also, as the power of pump light increases, the value of the Faraday rotation angle remains unchanged, but the maximum Faraday rotation frequency shifts to the lower frequencies. The noticeable changes in the transmission spectrum were not observed by changing the magnetic field strength and the pump light power.
