Query: Tunable graphene-based polarizer   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.
