Unified theory for Goos-Hänchen and Imbert-Fedorov effects
Unified theory for Goos-Hänchen and Imbert-Fedorov effects
A unified theory is advanced to describe both the lateral Goos-H\"anchen (GH) effect and the transverse Imbert-Fedorov (IF) effect, through representing the vector angular spectrum of a three-dimensional light beam in terms of a two-form angular spectrum consisting of its two orthogonal polarized components. From this theory, the quantization characteristics …
