Abstract

The polarization-dependent Hall effect of light was investigated in full-wave simulations for propagation of electron cyclotron waves in magnetized plasma as an anisotropic medium. The transverse shift of the wave packet, which is comparable to the wavelength in the vacuum, was observed in propagation of extraordinary (X) waves under a static magnetic field. This transverse shift is produced by the Berry curvature for the X wave strongly enhanced at the right-hand cutoff. The direction of the transverse shift is perpendicular not only to the gradient of the refractive index but also to the static magnetic field.
