11. Concluding Remarks
Using Super-computers and/or GPGPUs (General Purpose Graphic Processing Unit), acceleration technique of the electromagnetic simulation has been made a rapid progress. Owing to this background, electromagnetic simulation is widely used in developing IT products and services. This workshop was organized to study how the latest electromagnetic simulation is actually utilized in R & D field.
First, typical electromagnetic simulation methods were briefly summarized and pros and cons of each method were presented. Next, four case studies - (1) reflect array design to cover the blind area, (2) contactless power transmission, (3) communication including or adjacent to the human body and (4) EMC design at the upper phase of the development process - were presented. In each case, acceleration techniques such as GPGPU and engineering cloud are used. We realized that these techniques become indispensable for R & D field. We also discussed about the most suitable simulation method and modeling technique for some problems. This workshop was fruitful to have a deep understanding of the use of the electromagnetic simulation.
