In the previous works the spin Hall effect (SHE) of light was usually detected by the quantum weak measurement technique in which the complete information of the field was lost. In this work, we investigate the spatial evolution of the whole field in the SHE of light on reflection. First, we establish a model to describe the polarization state of reflected light and disclose its relationship with the SHE. Then, it is found that the reflected polarization generally becomes a vector field. The SHE due to the polarization gradient is manifested as a spin-dependent splitting. Further, it is found that both the incident angle and the incident polarization can affect the polarization of reflected light noticeably. Finally, the evolution of the energy flow is analyzed to disclose the underlying physical mechanism.
We extend the Green's function integral method to investigate the propagation of electromagnetic waves
through an anisotropic dielectric-magnetic slab. From a microscopic perspective, we analyze the interaction
of wave with the slab and derive the propagation characteristics by self-consistent analyses. Applying the
results, we find an alternative explanation to the general mechanism for the photon tunneling. The results
are confirmed by numerical simulations and disclose the underlying physics of wave propagation through
slab. The method extended is applicable to other problems of propagation in dielectric-magnetic materials,
including metamaterials.
