A method for numerically propagating a beam in the vicinity of an index discontinuity has been developed. Current methods of numerical beam propagation handle propagation up to the interface and beyond it, but not in the region where part of the beam is in one medium and the rest in the other. The new method allows an accurate modelling of the aberrations introduced by optics, e.g. steeply curved lens surfaces, where aberrations are introduced over a finite distance. The basic idea behind the method is to separately propagate the light which is in each of the refracting media.
