摘要: In this paper, we have reviewed our research on terahertz (THz) isolators and nonreciprocal transmission devices. addition, present a new kind of THz isolator based asymmetry magneto-metasurface. A structured InSb layer coats the silica substrate in which numerical simulation shows that metasurface has isolation over 60dB at 0.646 10dB operating bandwidth 13 GHz under an external magnetic field 0.3T with insertion loss less than 2.5dB. This low-loss, high isolation, easy coupling magneto-metasurface broadly potentials for application systems. Importantly, discuss conclude necessary conditions forming magneto-material devices, is strongly related asymmetric system.
