The bending loss of rays within circular and slab multimode optical waveguides is determined using only Snell's laws, the generalised Fresnel transmission coefficient and the Goos-Haenchen shift. The generalised transmission coefficient accounts for radiation losses, due to curvature, not included in Fresnel's classical laws.
