A physical optics approach to wavefront tracking is presented based on the stationary phase approximation. It allows for modeling transmission of radiation through a system of optical elements including coherence properties with an acceptable numerical effort. The code phase incorporating these ideas assumes small angles as it is the case for most synchrotron radiation and the free electron laser beam lines.
