Abstract: In this paper, we have reviewed our study in terahertz (THz) isolators and nonreciprocal transmission devices, with an emphasis on novel isolators based on a new kind of physical mechanism. In combination with microstructure and magneto-opitical material, we have presented different forms of THz isolators, such as plasmonic waveguides, plasmonic lens, photonic crystal cavity and magneto-metasurface. Moreover, we have discussed and concluded the necessary conditions of forming THz nonreciprocal transmission in the magneto-microstructure devices, which is strongly related with magneto-material and asymmetric transmission system. THz isolators are important for the realization high efficient THz systems.
