基于扰动非线性奇偶时间对称的无线实时电容读出
Wireless Real-Time Capacitance Readout Based on Perturbed Nonlinear Parity-Time Symmetry
摘要：
在这篇文章中，我们报告了一个矢量网络分析仪和实时LC无线电容读出系统的基础上扰动的非线性宇称时间（PT）对称性。该系统由两个电感耦合的读取器-传感器并联RLC谐振器组成，分别具有增益和损耗。通过搜索需要最小饱和增益的实模态，解析推导出了传感器电容扰动对稳态频率演化的影响。通过设置不同的扰动点，系统可以工作在不同的工作模式下。特别是，在PT对称的例外点，该系统表现出高灵敏度。实验表明，通过测量响应于传感器侧微调电容器的变化的读取器谐振器的稳态频率，所提出的读出机制的可行性。我们的发现可能会影响许多新兴的应用，如用于健康监测的植入式医疗设备，恶劣环境中的参数检测和密封食品包装等。
英文摘要：
In this article, we report a vector-network-analyzer-free and real-time LC wireless capacitance readout system based on perturbed nonlinear parity-time (PT) symmetry. The system is composed of two inductively coupled reader-sensor parallel RLC resonators with gain and loss respectively. By searching for the real mode that requires the minimum saturation gain, the steady-state frequency evolution as a function of the sensor capacitance perturbation is analytically deduced. The proposed system can work in different modes by setting different perturbation point. In particular, at the exceptional point of PT symmetry, the system exhibits high sensitivity. Experimental demonstrations revealed the viability of the proposed readout mechanism by measuring the steady-state frequency of the reader resonator in response to the change of trimmer capacitor on the sensor side. Our findings could impact many emerging applications such as implantable medical device for health monitoring, parameter detection in harsh environment and sealed food packages, etc.
