Goos–Hänchen and Imbert–Fedorov shifts for bounded wavepackets of light
We present precise expressions of the spatial and angular Goos-Hänchen and Imbert-Fedorov shifts experienced by a longitudinally and transversally limited beam of light (wave packet) upon reflection from a dielectric interface, as opposed to the well-known case of a monochromatic beam which is bounded in transverse directions but infinitely extended …
