标题： Tunable graphene-based polarizer

摘要： 证明了一种包含石墨烯层的衰减全反射结构可以作为电磁辐射的可调偏振器。 偏振角度通过调整施加到石墨烯上的电压来控制。 其机制基于$p-$极化的电磁波与石墨烯中表面等离子体-极化子的共振耦合。 所提出的计算表明，在共振时，反射波几乎 100% 是$s-$极化的。 显示英文摘要

摘要： It is shown that an attenuated total reflection structure containing a graphene layer can operate as a tunable polarizer of the electromagnetic radiation. The polarization angle is controlled by adjusting the voltage applied to graphene via external gate. The mechanism is based on the resonant coupling of $p-$polarized electromagnetic waves to the surface plasmon-polaritons in graphene. The presented calculations show that, at resonance, the reflected wave is almost 100% $s-$polarized.
