论文摘要
旋转磁化等离子体的旋转性能是分析得出的。机械旋转导致沿着磁场的波传播的新截止，并且高于此截止的极化旋转是经典的磁光光效应和机械光学极化阻力的总和。利用截止截止物附近的非常大的有效组索引，我们首次在这里暴露了极化阻力的$ 10^4 $比GHz频率下的Faraday旋转大。旋转导致弱吸收，同时允许直接控制频率控制，这表明了非转录元件的旋转等离子体的独特潜力。密集的非中性等离子体的非常大的旋转频率可以使THZ制度中前所未有的陀螺症。
The gyrotropic properties of a rotating magnetized plasma are derived analytically. Mechanical rotation leads to a new cutoff for wave propagation along the magnetic field and polarization rotation above this cutoff is the sum of the classical magneto-optical Faraday effect and the mechanico-optical polarization drag. Exploiting the very large effective group index near the cutoff, we expose here, for the first time, that polarization drag can be $10^4$ larger than Faraday rotation at GHz frequency. The rotation leads to weak absorption while allowing direct frequency control, demonstrating the unique potential of rotating plasmas for non-reciprocal elements. The very large rotation frequency of a dense non-neutral plasma could enable unprecedented gyrotropy in the THz regime.
