Web-based interactive 3D electromagnetic visualization for antenna designs

Electromagnetic radiation patterns are commonly visualized in 3D graphics to facilitate the design of antennas. Existing software are often proprietary and lack of interactive navigation capability for web users. A direct web-based visualization system with real-time interactive rendering capability can benefit EM education and facilitate research and development cycles significantly. This study demonstrates a pilot HTML5 deployment using WebGL-based browser with 3D graphics rendering power for electromagnetic data visualization. Detailed deployment method and exemplar rendering results are presented. The pilot deployment assures the future direction of cloud-based EM computation and web-based visualization.
