要約(英語): The method to express electromagnetic scatting processes, which are reflection, penetration, and diffraction, by using only radiating rays that are generated when an original ray collides into an obstacle is proposed. Every electromagnetic phenomenon is obtained through the straight-forward recurring process of collision and radiation of a ray. Simultaneous parallel execution of such a process enables to accelerate calculation of the electromagnetic field using ray-tracing method. A prototype of calculation engine by using the graphic card with GPU that has more than 0.3 million numeric cores achieves field calculations including these scatting processes in the area equal to one floor of usual office building in less than a minute.
