| Outline of Annual Research Achievements |
The purpose of this research was to develop a crosstalk mitigation method for a general wireless charging system of any scale and arrangement. We planned to study this problem in ideal condition of lossless transmission (work package [WP] 1), then improve the solution for lossy transmission (WP2), and refine the solution for the case when only partial transmission parameters are known (WP3). We also planned to investigate the power enhancing effect (WP4) and leaked magnetic suppressing effect (WP5) of using multiple transmitters and receivers.
In FY2020, we fulfilled WPs 1, 2, 3. The results from these WPs are significant. Thus, in FY2021 we have been performing further analysis and submitting to a major jounal (currently, still under review and revision). At the same time, we successfully developed a solution that is easy to implement for a special case of relayed wireless charging. We have published this new solution as a journal paper. As for WP4 and WP5, we have confirmed the effects of enhancing power and suppressing leaked magnetic field. These results need further analysis and are planned for future publications.
