OpenMaXwell is a graphic platform for Computational Electromagnetics and Computational Optics on personal computers under Windows 95/98/ME/NT/2000/XP/Vista/7/10. It was created by Ch. Hafner at ETH Zurich, Switzerland. OpenMaXwell includes:

• advanced tools for the visualization and animation of functions and fields
• a movie directive language interpreter for generating complicated movies
• a simple formula interpreter for defining complex grids, fields, material properties, grid transformations, etc.
• the latest 2D and 3D Multiple Multipoles (MMP implementations for accuratesemi-analytic computations
• Model-Based Parameter Estimation (MBPE) technique for fast evaluation of frequency  response
• standard 2D and 3D FDTD solvers.
