本文提出了一种基于倏逝波耦合机制的 13.56MHz 超材料，用于增强植入式生物医学设备中的无线电力传输 (WPT)。当发射和接收天线以 1 cm 距离和 1 cm 水平偏移放置时，超材料的功率传输效率 (PTE) 将从 46% 提高到 51%；当两个天线平面以 1.5 cm 的距离放置，轴向偏移 15° 时，超材料的功率传输效率 (PTE) 从 39% 提高到 46%；当两片超材料以 0.5 cm 的距离放置时，功率传输效率 (PTE) 从 28% 提高到 50%两个天线平面的放置距离为 1.5 厘米，水平偏差为 1 厘米。
This paper presents a 13.56MHz metamaterial for wireless power transmission (WPT) enhancement in implantable biomedical devices based on the evanescent wave coupling mechanism. The power transmission efficiency (PTE) will increase from 46 to 51% with the metamaterial while the transmitting and receiving antennas are placed with a 1 cm distance and 1cm offset horizontal misalignment, will increase from 39 to 46% with the metamaterial while the two antenna planes are placed at a distance of 1.5 cm with an axial offset of 15°, and will increase from 28 to 50% with two pieces of metamaterial placed with a 0.5cm distance while the two antenna planes are placed with a 1.5 cm distance and 1 cm offset horizontal misalignment.
