Monday 16 Nov, 11:00 – 11:45
Abstract: Wireless power transfer technologies using magnetic field resonance can give us a freedom from hardwired connectivity, especially when supplying electrical powers to mobile platforms, home appliances, and automotives. In addition, we can reduce the cost of system power wirings, and will be able to reduce capacity and weight of batteries at the same time.
In this presentation, first, we will explain basic principles of the wireless power transfer using the magnetic field resonance as well as necessary modelling approaches and simulation methods including active and passive shielding. In particular, we will present meta-material design and implementation cases for enhanced power efficiency and EMI reduction. Finally, we will discuss the possibilities of novel artificial intelligence and machine learning methods including deep neural network and reinforcement learning, to support design and optimization processes of the wireless power transfer circuits, coils and shielding systems.

Perspective of Wireless Power Transfer in Next Decade
Naoki Shinohara, Kyoto University, Japan
Tuesday 17 Nov, 11:15 – 12:00
Abstract: Last decade was rediscovery and growth period of wireless power transfer (WPT) technologies. After revolution of resonance coupling WPT, which is one of near field WPT, by Massachusetts Institute of Technology, great number of people re-found the WPT is interesting and hopeful technology and started research and development (R&D) of the WPT, not only the near field WPT but also far field WPT including energy harvesting from ambient radio waves. Now we are moving the WPT from R&D to industry with discussion for radio regulation of the WPT. In next decade, what happens in the WPT? Is it still hopeful and game changing technology or the end of the R&D trend? In this talk, based on the history and current R&D status of the WPT, I give hopeful trend of the WPT R&D, industry, and radio regulation in next decade.
