| Outline of Final Research Achievements |
In the field of electrical engineering, engineers who understand electric and magnetic phenomena are required. However, the phenomena are invisible and difficult to understand for beginners. In this research, we proposed an educational simulator to visualize an electromagnetic field in a three dimensional virtual reality (VR) field.
We developed a finite-difference-time-domain electromagnetic field simulation system. In this research, GPU programming is attached to the system for improving the simulation speed. By using more than 100 GPU threads, the speed was reduced to 0.1 second per time step, and it is suitable for education. Furthermore, the electric circuit simulation model consisting of a parallel plate capacitor and DC voltage supply was developed and applied for education. As a result, good comments for the developed VR system are obtained.
