Compact WPT system for concurrent transfer of data and power using metamaterial diplexer receiver

在这项联合研究中，我们能够使所谓的人工介质具有负磁导率，也就是我们所知的用于近场WPT系统的超材料。我们提出了这种超材料的条件，并提出了一种新型的三维构型超材料来满足这些条件。我们还提出了一种简单、紧凑、高效的WPT系统，可以同时将功率和信号传输到生物医学植入物或嵌入式医疗设备。在协作工作中，许多想法是共同发明的，其中一些想法是由东道主研究人员在简明扼要的时间内显著而有效地实施的。研究成果发表在多个高引文期刊和国际会议/研讨会上，发表了三部著作。在工作1中，同时使用无线电力和信息传输系统的耦合共存的有缺陷的接地结构。在工作2中，提出了利用耦合共存的缺陷接地结构和8字形电感实现同时无线功率和信息传输系统。在工作3中，提出了一种受超曲面启发的新型几何结构，用于生物医学应用的紧凑型WPT系统。在这项研究中，提出了一种新型的堆叠结构的超表面，使其更紧凑，更容易与接收器集成。

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.
