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 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 nonreciprocal elements. The very large rotation frequency of a dense non-neutral plasma could enable unprecedented gyrotropy in the THz regime.

旋转等离子体中增强的可调旋转功率

旋转磁化等离子体的回旋特性通过分析得出。机械旋转导致波沿着磁场传播的新截止，并且在该截止上方的极化旋转是经典的磁光法拉第效应和机械光极化阻力的总和。在截止点附近利用非常大的有效群指数，我们在这里暴露出极化拖曳可以是${10}^4$大于法拉第旋转频率（GHz）。旋转导致吸收弱，同时允许直接进行频率控制，这证明了旋转等离子在不可逆元素上的独特潜力。稠密的非中性等离子体的非常大的旋转频率可以在太赫兹范围内实现空前的回旋。
