High-Data-Rate Long-Range Underwater Communications via Acoustic Reconfigurable Intelligent Surfaces
IEEE Communications Magazine, 2022Despite decades-long development, underwater communication systems still cannot achieve high data rates and long communication ranges at the same time (i.e., beyond 1 Mb/s and 1 km).
