In this study, the authors propose an innovative solution based on mantle cloaking method to restore the performance of an implantable antenna, which is degraded due to the scattering from an adjacent metallic body. In an implantable device, the metallic body is generally used as a house for electronic circuitry. Initially, they investigate the deteriorating effects of metallic body on the antenna input impedance and radiation characteristics. Finally, by covering the metallic body with the designed metasurface, most of the antenna parameters are successfully retrieved. The proposed model is fabricated and measured with the in vitro test by immersing the antenna inside a muscle emulating gel, as well as, inside the minced pork.

在可植入场景中恢复金属圆柱附近的天线性能

在这项研究中，作者提出了一种基于披风掩盖法的创新解决方案，以恢复可植入天线的性能，该天线由于邻近金属物体的散射而退化。在可植入装置中，金属体通常用作电子电路的外壳。最初，他们研究金属物体对天线输入阻抗和辐射特性的恶化影响。最终，通过用设计的超表面覆盖金属主体，可以成功检索大多数天线参数。通过将天线浸入模拟肌肉的凝胶以及猪肉末内部，通过体外测试来制造和测量提出的模型。
