Wireless connectivity and networks have experienced dramatic growth in the past decade, benefiting society in commerce, information access, transportation, health, and defense. With strong commercial demand of the spectrum such as for mobile broadband wireless access, the passive uses of spectrum such as radio astronomy and atmospheric science, along with critical active non-commercial services such as global positioning system and weather radar, have been increasingly encroached. Furthermore, the resulting electromagnetic spectrum below 60 GHz have become increasingly overcrowded, bounded by the carrier frequency, even with spectrum-efficient advanced modulation and multi-input multi-output spatially diverse network protocols. In contrast, the electromagnetic spectrum between 300 GHz to 850 GHz is largely unassigned. This provides a unique opportunity to utilize this range of the electromagnetic spectrum, without spectrum crowding and with significant spectrally dense capacity enhancement, while designing a priori the coexistence with passives uses in radio astronomy and atmospheric science. The sub-millimeter wave (smmWave) and terahertz (THz) regions have unique rich spectral signatures for atmospheric constituents and molecules as well as for astronomical science observation, in both thermal emission and rotational-vibrational emission lines. This project seeks to demonstrate the co-designed physical and network layers in the high-data-rate smmWave communication link with the presence of passive uses in atmospheric science and radio astronomy. Chip-scale measurements, designs and nanofabrication will be studied, together with the information theoretic and architectural aspects of the smmWave active-passive communication network. The project will integrate the research with various educational and outreach activities to recruit undergraduate and high-school students from underrepresented minority groups in STEM. This project examines a smmWave communication link in directed point-to-point connectivity, in the presence of coexisting smmWave passive-use systems in atmospheric science and radio astronomy. To enable the cross-layer integration, the research will examine proof-of-concept measurements in each of the scientific Thrusts, together with a co-designed communication-sensing testbed. Thrust 1 will examine a photonic-smmWave link and sensing module, with an integrated chip-scale transmitter-receiver-detector block. The narrow-linewidth smmWave radiation encodes high-speed data per channel, with the directed beam coupled to a reconfigurable antenna array for dynamic phase-array beam steering. Four channels will be demonstrated in the link prototype, with a high-sensitivity large dynamic range heterodyne photomixed receiver. In Thrust 2, an adaptive communications testbed will be examined, in the presence of passive users. Spectrally dense scaling and energy-per-bit efficiencies will be studied, along with concurrent passive detection of smmWave molecular spectral signatures. Thrust 3 will study the directivity beam steering of the smmWave link to guarantee low interference for passive users. Spatial footprint, fundamental bounds on the network capacity, multi-input multi-output and sensing schedules will be quantified. An expanded network with multiple source-destinations and passive users will be studied.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.

在过去的十年中，无线连通性和网络经历了巨大的增长，从而使社会在商业，信息获取，运输，健康和防御方面受益。随着频谱的强劲商业需求，例如移动宽带无线访问，诸如射电天文学和大气科学等光谱的被动用途以及关键的主动非商业服务（例如全球定位系统和天气雷达）越来越受到侵蚀。此外，即使使用频谱高效的高级调制和多输入多输出的空间多样性网络协议，也会越来越多地拥挤，低于60 GHz的电磁频谱已经变得越来越拥挤。相反，在300 GHz至850 GHz之间的电磁光谱在很大程度上没有分配。这提供了一个独特的机会，可以利用这一范围的电磁频谱，而没有光谱拥挤，并且具有显着的频谱密集能力增强，同时设计了与被动射击天文学和大气科学中的被动用途共存。在热发射和旋转振动发射线中，次毫米波（SMMWAVE）和TERAHERTZ（THZ）区域具有独特的大气成分和分子以及天文学科学观察的独特光谱特征。该项目旨在证明高数据速率SMMWave通信链接中的共同设计的物理和网络层与大气科学和射电天文学中的被动用途的存在。将研究芯片尺度的测量，设计和纳米化，以及SMMWave主动通信网络的信息理论和架构方面。该项目将将研究与各种教育和外展活动相结合，以招募来自STEM中代表性不足的少数群体的本科生和高中生。该项目研究了在大气科学和射电天文学中共存的SMMWave被动使用系统的情况下，在有定向点对点连接性的SMMWave通信链接中。为了实现跨层的整合，研究将检查每个科学推力的概念概念验证测量，以及共同设计的通信测试台。推力1将检查具有集成的芯片尺度发射器接收器检测器块的光子-SMMWAVE链路和传感模块。狭窄的线宽SMMWAVE辐射每个通道都编码高速数据，定向光束耦合到可重新配置的天线阵列，以进行动态相阵列光束转向。链路原型将展示四个通道，具有高敏感性大动态范围杂作偶像接收器。在推力2中，将在被动用户的存在下检查自适应通信测试床。将研究光谱密集的缩放和每位能量效率，并同时被动检测SMMWAVE分子光谱特征。推力3将研究SMMWave链接的方向性光束转向，以确保对被动用户的干扰低。将量化空间足迹，网络容量的基本界限，多输入多输出和感应时间表。将研究一个具有多种源探测和被动用户的扩展网络。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响评估标准，被认为值得通过评估来获得支持。
