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

在这项联合研究中，我们能够制造出所谓的具有负磁导率的人工材料，也称为超材料，将用于近场WPT系统。我们提出了这种超材料的条件，并提出了一种新型的三维结构的超材料，以满足这些条件。我们还提出了一个单一的紧凑和高效率的WPT系统，可以同时将电源和信号传输到生物医学植入物或嵌入式医疗设备。在合作工作中，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提出的，并由JSPS研究员在一个简短的时间内显着有效地实施。结果发表在许多高引用的交易和国际会议/研讨会。在工作1中，同时使用耦合共存的缺陷接地结构的无线电力和信息传输系统。在工作2中，提出了使用耦合共存的缺陷接地结构和8字形电感器来实现同时无线功率和信息传输系统。在工作3中，提出了一种新型的超表面启发的几何形状，用于生物医学应用的紧凑WPT系统。在这项研究中，提出了一种新型的超颖表面与堆叠配置，使其更紧凑，易于与接收器集成。

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.
