| Outline of Annual Research Achievements |
In this joint research, we were able to make the so-called artificial dielectrics having negative permeability which is also known as metamaterial that will work for nearfield WPT system. We proposed the condition for such metamaterial, and we also proposed a new type of metamaterial in 3D configuration to satisfy these conditions. We also proposed a single compact and high-efficiency WPT system that can transfer the power and signal concurrently to biomedical implants or embedded medical devices. In the collaborative work, many ideas were invented jointly, and some of them by the host researchers and implemented by the JSPS fellow in a concise period remarkably and effectively. The results were published in many highly referred transactions and international conferences/symposium.We publisehd three works. In Work 1 where simultaneous wireless power and information transfer system using coupled co-existing defected ground structures. In Work 2 where simultaneous wireless power and information transfer system using coupled co-existing defected ground structures and figure-8 inductors is proposed realized. In work 3 where new type of metasurface-inspired geometry was proposed for compact WPT system for biomedical applications. In this study, a new type of metasurface with the stacked configuration is proposed to make it more compact and easy to integrate with the receiver.
