    "abstract": "A unified theory is advanced to describe both the lateral Goos-H\\\"{a}nchen\n(GH) effect and the transverse Imbert-Fedorov (IF) effect, through representing\nthe vector angular spectrum of a 3-dimensional light beam in terms of a 2-form\nangular spectrum consisting of its 2 orthogonal polarized components. From this\ntheory, the quantization characteristics of the GH and IF displacements are\nobtained, and the Artmann formula for the GH displacement is derived. It is\nfound that the eigenstates of the GH displacement are the 2 orthogonal linear\npolarizations in this 2-form representation, and the eigenstates of the IF\ndisplacement are the 2 orthogonal circular polarizations. The theoretical\npredictions are found to be in agreement with recent experimental results.",
