Objective:We seek to increase sensitivity of antenna-coupled infrared detectors by an order of magnitude. We will gain understanding of relevant design parameters, and subsequently design impedance-matched antenna-sensor combinations. We utilize our newly developed high-spatial-resolution, three-dimensional probe techniques to measure electric fields in the vicinity of the infrared antennas. This enables us, for the first time, to determine the infrared-frequency impedance as a function of position. Combined with an iterative design-fabrication-test approach, this will enable development of infrared impedance-matching components.Intellectual merit:We scale up the concept of a radiofrequency network analyzer by nine orders of magnitude in frequency. This proven advance yields experimental tools needed to extend the performance of antenna-coupled sensors by a similar scale in frequency, making the entire field of passive low-5frequency electronics operational in the infrared range. Infrared antennas have been proposed for a wide range of applications, including nanoscale chemical and photon sensors, nearfield microscopy, and optical rectennas for energy-harvesting. Such devices would transform the field of optics, enabling sensing devices of nano-scale dimensions with order-of-magnitude enhancement in sensitivity, responsivity, and reliability compared to conventional optical techniques.Broader impact:The proposed research greatly extends the frequency range of classical electronics, while serving as the foundation for a dynamic and engaging learning environment at each of the PIs? institutions. All three PIs have an established track record of mentorship of underrepresented students, and all three participate in programs for science and engineering outreach to K-12 students and research participation of undergraduate students.

目的：将天线耦合红外探测器的灵敏度提高一个数量级。我们将了解相关的设计参数，然后设计阻抗匹配的天线-传感器组合。我们利用我们最新开发的高空间分辨率三维探测技术来测量红外天线附近的电场。这使我们第一次能够确定红外频率阻抗作为位置的函数。结合迭代设计-制造-测试方法，这将使红外阻抗匹配组件的开发成为可能。智能优势：我们将射频网络分析仪的概念扩大了9个数量级的频率。这一成熟的进步产生了所需的实验工具，以将天线耦合传感器的性能在类似的频率范围内扩展，使整个无源低频电子设备领域在红外范围内运行。红外天线已经被提出用于广泛的应用，包括纳米级的化学和光子传感器、近场显微镜和用于能量收集的光学整流管。这类器件将改变光学领域，使纳米尺度的传感器件在灵敏度、响应性和可靠性方面与传统光学技术相比有数量级的提高。广泛影响：拟议的研究极大地扩展了经典电子学的频率范围，同时为每个PI？机构。这三家私人投资机构都有为代表不足的学生提供指导的既定记录，并且都参与了面向K-12学生的科学和工程拓展项目以及本科生的研究参与。
