The National Science Foundation (NSF) awarded a $340,000 Project Grant under the Computer and Information Science and Engineering (CFDA 47.070) program to the Board of Regents of the University of Nebraska for a collaborative research project titled "NETS: MEDIUM: DESIGN AND ALGORITHMS FOR ACTIVE RECONFIGURABLE INTELLIGENT SURFACES FOR SUB-THZ WIRELESS NETWORKS."
The key products and services to be delivered through this award include: 1) Design and prototyping of a wideband liquid crystal-based reconfigurable intelligent surface (RIS) operating at 142 GHz to improve wireless coverage and efficiency in sub-terahertz (sub-THz) communications; 2) Development of robust and efficient algorithms for optimal control of the active RIS elements, leveraging techniques like unsupervised graph neural networks and reinforcement learning; and 3) Extensive validation and characterization of the active-RIS-aided sub-THz wireless propagation using simulation tools and on-site measurement campaigns. The project aims to advance sub-THz wireless networking capabilities to enable high-speed, low-power wireless connectivity required for future 6G communication systems.
