Hentschel, Martina and Schomerus, Henning (2002) Fresnel laws at curved dielectric interfaces of microresonators. Physical Review E, 65. 045603.
We discuss curvature corrections to Fresnelâ��s laws for the reflection and transmission of light at a nonplanar refractive-index boundary. The reflection coefficients are obtained from the resonances of a dielectric disk within a sequential-reflection model. The Goos-HÃ¤nchen effect for curved light fronts at a planar interface can be adapted to provide a qualitative and quantitative extension of the ray model which explains the observed deviations from Fresnelâ��s laws.
