Outline of Final Research Achievements

This research is titled as “Study on Realization of Ubiquitous Energy Society by Magnetic Resonance Coupling”. This project focuses on N- N wireless power transfer system. It is composed by multiple transmitters and multiple receivers. In four years, this project has achieved the following important results: 1) clarification of the phenomenon causing an improvement of total efficiency under wireless power transfer from multiple systems, 2) cross coupling cancelling method, 3) simultaneous maximum efficiency and desired power control at secondary side, 4) creation of robust wireless power transfer system, 5) formulation of an unified theory of magnetic resonant coupling and electromagnetic induction, 6) suppression of leakage electromagnetic wave.
Many other results have also been reached. I got many achievements throughout this project, therefore I can conclude that this project has been completed successfully.
