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.

无线连接和网络在过去十年中经历了急剧的增长，使社会在商业、信息访问、交通、健康和国防方面受益。随着对诸如移动的宽带无线接入之类的频谱的强烈商业需求，诸如射电天文学和大气科学之类的频谱的被动使用以及诸如全球定位系统和气象雷达之类的关键主动非商业服务沿着被越来越多地侵占。此外，所产生的低于60 GHz的电磁频谱已经变得越来越拥挤，受到载波频率的限制，即使使用频谱高效的高级调制和多输入多输出空间多样性网络协议。相比之下，300 GHz至850 GHz之间的电磁频谱在很大程度上未分配。这提供了一个独特的机会，利用这一范围的电磁频谱，没有频谱拥挤和显着的频谱密集的能力增强，同时设计了先验的共存与被动使用在射电天文学和大气科学。亚毫米波（smmWave）和太赫兹（THz）区域在热发射和旋转振动发射线中具有独特的丰富光谱特征，用于大气成分和分子以及天文科学观测。该项目旨在展示高数据速率smmWave通信链路中共同设计的物理层和网络层，以及大气科学和射电天文学中的被动用途。芯片级的测量，设计和nanofabbits将研究，连同信息理论和架构方面的smmWave有源无源通信网络。该项目将把研究与各种教育和推广活动结合起来，从STEM中代表性不足的少数群体中招募本科生和高中生。该项目研究了在大气科学和射电天文学中共存的smmWave被动使用系统中，定向点对点连接的smmWave通信链路。为了实现跨层集成，该研究将检查每个科学推力中的概念验证测量，以及共同设计的通信传感测试平台。推力1将检查光子-smmWave链路和传感模块，以及集成的芯片级发射器-接收器-检测器模块。窄线宽smmWave辐射对每个通道的高速数据进行编码，定向波束耦合到可重新配置的天线阵列，用于动态相控阵波束转向。四个通道将在链路原型中演示，具有高灵敏度大动态范围外差光混合接收器。在推力2中，将在被动用户存在的情况下检查自适应通信试验台。将研究光谱密集缩放和每比特能量效率，沿着同时被动检测smmWave分子光谱特征。重点3将研究smmWave链路的方向性波束控制，以保证对被动用户的低干扰。空间足迹，网络容量的基本界限，多输入多输出和传感时间表将被量化。该奖项反映了NSF的法定使命，并已被认为值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。
