This National Science Foundation (NSF) Computer and Information Science and Engineering (CISE) Federal Grant Program (CFDA 47.070) award of $200,000 to New York University (NYU) will support research to design and prototype a wideband liquid crystal-based reconfigurable intelligent surface (RIS) operating at 142 GHz. The project aims to develop novel algorithms for optimal control of the active RIS elements, including frequency-dependent phase shift and amplitude amplification, leveraging unsupervised graph neural networks and reinforcement learning. Additionally, the team will perform extensive validation using simulation tools and on-site wireless propagation measurements to create a hybrid channel model for RIS-aided sub-terahertz communications. The project spans from October 1, 2024 to September 30, 2027 and is focused on advancing technology for high-speed wireless connectivity and ubiquitous network access in the sub-terahertz frequency bands.
