Acoustic Ultra-Massive MIMO: closing the underwater bandwidth gap
Our 2024 JSAC paper proposes a graphene-plasmonic transducer array enabling hundreds of simultaneous acoustic streams over fjord-scale ranges — a step change from single-channel sonar-era links.
Abstract excerpt: “We introduce an ultra-massive transducer architecture exploiting the low attenuation of low-frequency acoustic bands and the spatial multiplexing gains of large-aperture arrays. Field trials in Hvalfjörður demonstrate a 47× throughput improvement over conventional single-element acoustic modems, at ranges exceeding 2.1 km, without surface infrastructure.”
