Spin Hall Effect Enhancement of Transmitted Light Through an Anisotropic Metamaterial Slab

We study the spin Hall effect (SHE) enhancement of transmitted light through an anisotropic metamaterial slab. Physical mechanism of large transverse shift is explained based on the coupling between spin angular momentum and orbit angular momentum. Theoretical analysis predicts large transverse shif...
