Schematics of the atomically thin and polarization-selective optical isolation for circularly polarized waves.

An external magnetic field is applied perpendicular to graphene plane. Only one circularly polarized wave can propagate through the gyrotropic graphene in one propagation direction. The arrows in the helixes show the instantaneous electric field distributions of circularly polarized waves.
