In this optimization, the magnetic core shape is represented by the linear combination of the normalized Gaussian functions. The core shape is optimized so that the coupling coefficient between the transmitting and receiving coils is maximized. Moreover, robustness against misalignment between the coils is taken into account in the optimization. It is found that the optimized core shape effectively increases the net magnetic flux interlinked with the receiving coil, and outperforms the conventional core shapes.IOS PressJournal Articleapplication/pdfhttp://hdl.handle.net/2115/76839https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/76839/1/Full_paper_final_submission_IJAEM.pdf1383-54161875-8800AA11051133International journal of applied electromagnetics and mechanics60S1S115S1232020-03-02enginfo:doi/10.3233/JAE-191110The final publication is available at IOS Press through http://dx.doi.org/10.3233/JAE-191110author
