It can simulate wave reflection and diffraction in 2D. It allows to visualize the electric field magnitude. The original approach is based on discrete analytical geometry allowing a dynamic visualization of the wave propagation contrary to existing models. We use it for the moment as pedagogic tool for the understanding of this complex phenomenon.
