Atmospheric Effects on Terahertz Wireless Communications

这项研究的目的是评估大气湿度、空气中的微粒（如雨、雾和烟）和折射率波动（闪烁）对无线太赫兹通信链路的影响。该方法是表征100 - 2,000 GHz的太赫兹通信链路，并将其性能与自由空间红外链路进行比较。红外线和太赫兹辐射将在相同的大气条件下共传播。将制造几个腔室来产生各种大气条件，包括雾、烟、雨以及传播光束路径内的闪烁。智力优势：该研究将提供各种大气条件下太赫兹传播的实验测量和表征，可用于比较和验证各种太赫兹辐射的传播模型。太赫兹和红外无线通信链路的性能，由误码率、眼图、传输功率损失、数据速率和其他参数决定，将在相同的大气条件下进行比较。更广泛的影响：该项目的更广泛影响包括开发用于研究生和本科生教育和研究的综合实验室模块，来自代表性不足群体的学生参与研究项目，以及将教育模块和科学数据广泛传播给从事大气建模和无线太赫兹通信研究的其他团体。

The objective of this research is to assess the effects of atmospheric humidity, airborne particulates (such as rain, fog and smoke), and refractive index fluctuations (scintillations) on wireless THz communication links. The approach is to characterize a THz communication link from 100 - 2,000 GHz and compare its performance to a free-space infrared link. Both the infrared and THz radiation will co-propagate through the same atmospheric conditions. Several chambers will be fabricated to generate a variety of atmospheric conditions including fog, smoke, rain, as well as scintillations within the propagating beam path.Intellectual Merit: The research will provide yet unavailable experimental measurements and characterization of THz propagation under a variety of atmospheric conditions, which can be used to compare and validate various propagation models of THz radiation. The performance of THz and infrared wireless communication links, as determined by bit error rates, eye diagrams, transmitted power loss, data rate, and other parameters, will be compared under the same atmospheric conditions. Broader Impacts: The broader impacts of the project include the development of integrated laboratory modules for use in graduate and undergraduate education and research, the participation of students from underrepresented groups in the research project, and the broad dissemination of educational modules and scientific data to other groups conducting research in atmospheric modeling and wireless THz communications.
