2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/224872We present here a compactly formulated application of the previously posted general formalism of the reflection of Gaussian beams at a dielectric interface ({arXiv:0710.1643v2 [physics.optics]}). Specifically, we calculate the Goos-Hänchen shift near Brewster incidence, for an air-glass plane interface.13 pages, 2 figures. V2: A few typos corrected, a new section addedOpticstext
