Abstract

Recent development in classical electrodynamics has demonstrated the usefulness of different rotational and topological modes in the electromagnetic fields (angular momentum; polarization; vorticity etc.). Unfortunately; the visualization tools available to illustrate these electrodynamic quantities have hitherto been inadequate. Therefore we have developed a VTK and Python based interactive visualization tool; with working name EMVT (ElectroMagnetic Visualization Tool); targeted at visualizing precisely these modes. In the near future; EMVT will be further developed to visualize and control live antenna systems; where electromagnetic field data is instantly received; calculated; and visualized from an antenna or a system of antennas. It will then be possible to see how the antenna properties change through direct user interaction in real time.
