The proposed instrumentation is a 220-GHz vector network analyzer (VNA). A VNA is usually the heart of a high-frequency test lab for measuring both the magnitude and phase of scattering parameters such as the reflection and transmission coefficients of materials, devices and circuits. The proposed ultra-wideband VNA will enable the research on nanoelectronics materials and devices for future generation of wireless communication and Internet of Things above 110 GHz at Cornell and worldwide. The knowledge and experience gained in the research up to 220 GHz will serve as the foundation for research in the terahertz frequency range. Additionally, the proposed VNA will enhance the research on quantum-computing devices, microelectromechanical sensors, biosensors, high-speed integrated circuits, energy-efficient power devices, and sensors for cosmic radiation. Among NSF’s 10 big ideas, the research enabled or enhanced by the proposed VNA will impact ideas for Future of Work, Quantum Leap, Understanding the Rules of Life, and Windows on the Universe. The proposed VNA will be part of the Cornell NanoScale Facility (CNF), which has a long and excellent history in providing efficient access to nanotechnology infrastructure and expertise, as well as operating and maintaining major research instrumentation. CNF, in turn, is part of the NSF-supported National Nanotechnology Coordinated Infrastructure with national impact. Evidenced by the letters of collaboration, there is a world-wide interest in using the proposed VNA. The interested users include those from major research universities, historically black colleges and universities, minority serving institutions, major companies, and start-ups.The proposed ultra-wideband VNA will be one of the firsts in the world. It was announced by the Anritsu Company last year and is uniquely based on the newly developed 0.6-mm-diameter coaxial components, making it possible for measurements with a single and continuous sweep of frequencies from 70 kHz to 220 GHz. This is fundamentally different from conventional VNAs that are based on waveguides with segmented bandwidths above 110 GHz. As the result, the proposed broadband VNA will enable large-signal nonlinear measurements of gain-compression, amplitude-to-phase distortion, harmonic generation, intermodulation, time-domain reflectivity, noise, etc. The proposed VNA will enable pulsed measurements, which are critical to high-power devices. In the future, the proposed VNA can be retrofitted with frequency extenders to extend its bandwidth to 1.1 THz."This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

所提出的仪器是220-GHz矢量网络分析仪（VNA）。 VNA通常是高频测试实验室的核心，用于测量散射参数的大小和相位，例如材料，设备和电路的反射和传输系数。拟议的超宽带VNA将使对纳米电子学材料和设备进行研究，以实现未来的无线通信以及在康奈尔州和全球110 GHz以上的物联网。在高达220 GHz的研究中获得的知识和经验将成为Terahertz频率范围研究的基础。此外，所提出的VNA将增强对量子计算设备，微电机电传感器，生物传感器，高速集成电路，节能功率设备以及宇宙辐射传感器的研究。在NSF的10个大想法中，该研究由拟议的VNA启用或增强，将影响未来的工作，量子飞跃，了解生活规则以及宇宙中的窗户的想法。拟议的VNA将成为康奈尔纳米级设施（CNF）的一部分，该设施具有悠久而出色的历史，可为纳米技术基础设施和专家提供有效的访问，以及运营和维护主要的研究工具。反过来，CNF是NSF支持的国家纳米技术协调基础设施的一部分。合作信的证明，使用拟议的VNA具有全球范围的兴趣。感兴趣的用户包括来自主要研究大学，历史悠久的黑人学院和大学，少数派服务机构，主要公司和初创企业的用户。拟议的超宽带VNA将是世界上第一个。它是由Anritsu公司去年宣布的，它是基于新开发的0.6毫米直径的同轴组件的独特之处，这使得可以进行一次且连续的频率从70 kHz到220 GHz的频率进行测量。这与基于在110 GHz高于110 GHz的段带宽的波导的传统VNA根本不同。结果，所提出的宽带VNA将实现增益 - 压缩，放大器到相的失真，谐波产生，谐波，调整，时间域反射率，噪声等的大信号非线性测量。所提出的VNA将启用脉冲测量，这些测量对于高电力设备至关重要。将来，提出的VNA可以对频率扩展器进行改造，以将其带宽扩展到1.1 THZ。
