Abstract
The spin-polarized injections through the lateral interface between two regions with different strengths of spin-orbit interactions have been investigated. In the presence of the spin-orbit coupling of both Rashba and Dresselhaus types, the phenomena of negative refraction of spintronics have been found. An electron beam with some angles of incidence after passing through such an interface splits into two beams with different spin polarizations propagating in negative and positive directions, respectively. Thus, a spin beam splitter has been proposed based on such an interface.
