随着纳米技术的进步，新型纳米传感技术可以在当今社会中发挥关键作用。等离子体传感已被证明可以在非常紧凑的外形中提供前所未有的检测可靠性和分辨率。传统的等离子体传感器利用生物功能化的金属光栅结构，其在透射和/或反射中的频率响应根据靶向生物标志物的存在而改变。然而，这些感测设置需要使用庞大的测量设备来将光耦合到传感器和从传感器耦合光以用于激发和检测。与此同时，十多年来，纳米级电磁通信社区一直在利用等离子体结构来有效地传输纳米级信息。结合这两个领域，本文提出了利用等离子体传感纳米天线实现纳米级联合通信和传感的概念。首先，对生物功能化等离子体纳米天线在暴露于不同生物标志物时的频率响应的变化进行建模。然后，提出了一种啁啾扩频激励和检测系统，作为一种方式，使同时通信和传感在纳米级。数值结果证明了所提出的系统的性能。
With the advances in nanotechnology, novel nanosensing technologies can play a pivotal role in today's society. Plasmonic sensing has been proven to provide unprecedented detection reliability and resolution in a very compact form factor. Traditional plasmonic sensors leverage biofunctionalized metallic grating structures whose frequency response in transmission and/or reflection changes according to the presence of targeted biomarkers. However, these sensing setups require the use of bulky measurement equipment to couple light to and from sensors for excitation and detection. In parallel, for over a decade, the nanoscale electromagnetic communication community has been leveraging plasmonic structures to efficiently transmit information at the nanoscale. By combining the two realms, in this paper, the concept of joint nanoscale communication and sensing enabled by plasmonic sensing nano-antennas is proposed. First, the changes in the frequency response of a biofunctionalized plasmonic nano-antenna when exposed to different biomarkers are modeled. Then, a chirp-spread spectrum excitation and detection system is proposed as a way to enable simultaneous communication and sensing at the nanoscale. Numerical results are provided to demonstrate the performance of the proposed system.
