Magnetic n-gon Billiards
Magnetic n-gon Billiards
This Demonstration shows the path of a magnetic billiard ball. In classical billiards, the paths are assumed to be straight. In magnetic billiards, the paths of the particles are circle segments, modeling the trajectory of a charged particle in a perpendicular homogeneous magnetic field. Another contrast to classical billiards is that magnetic billiards allows for outside trajectories that traverse the billiard table on the outside. (Such trajectories can be observed in modern semiconductor nanostructures, such as quantum antidot arrays.) For a finite thickness and repeated reflections, interesting interference patterns can arise.
