Adjustable magnetic reflection and focusing of an 87Rb Bose-Einstein condensate was achieved using a particularly smooth mirror and a very straightforward apparatus. In this paper, we discuss a simple Thomas-Fermi model and a Monte Carlo method for analysing the bouncing. Both models are in close agreement with the observed condensate evolution. Additionally, the theory predicts very tight condensate focusing, and atomic matter-wave diffraction should be observable. The effect of mirror anharmonicities on the condensate focusing is investigated.
