With electromagnetic theory of light, We found that the polarizationof the light kept the same when the reflection of incident light satisfied critical reflection or dual-quadrature reflection.
Further analysis of the contact interface and a more complete theory are needed to extract a reliable spin polarization message with the point contact Andreev reflection method.
The system of typical surface feature polarizationreflection databases was set up in a computer in order to give service to the study ofpolarization remote sensing information.
