An analytical approach to extend Fresnel laws to concave shaped interfaces — •Sebastian Luhn and Martina Hentschel — Institute for Physics, Group for Theoretical Physics II / Computational Physics, Technische Universität Ilmenau, Weimarer Str. 25, 98693 Ilmenau, Germany

Optical microcavities play an important role in many modern research fields. In particular it is interesting to study the reflection and refraction of beams at the interfaces of these cavities. The reflection of beams is described by Fresnel*s laws which apply to flat surfaces only and need to be corrected for curved interfaces. Since convex interfaces have been studied already, we perform these cor- rections for concave interfaces. We obtain the reflection coefficients by extend- ing the model of transfer matrices to cylindrical interfaces. Additionally we gain a relation between convex and concave Fresnel coefficients.
