Optical microcavities have important applications in various fields of physics; deformed optical microdisks in particular attract interest in the quantum chaos community because they can be used to study ray-wave correspondence in open systems both theoretically and experimentally. As smaller and smaller cavities can be fabricated, corrections to the ray picture become important. Unfortunately, analytical formulas for the lowest-order corrections (so-called Goos-Hänchen shift and Fresnel filtering) only exist for certain limiting cases. Here, we present a method that allows the numerical calculation of there corrections; the corrections can be applied to the full phase space, which is not possible using the analytical results. We present results for the extended ray dynamics of elliptical and Limacon-shaped microdisks and compare them to wave calculations.
