Course Description

Overview

Explore a 15-minute conference talk from USENIX NSDI '23 that delves into innovative acoustic sensing and communication techniques using metasurfaces. Learn about the advantages of acoustic metasurfaces (AMS) over phased array speakers, including significant SNR improvements while maintaining compact size. Discover a novel acoustic system that combines metasurfaces with a small number of speakers to achieve low-cost dynamic steering. Gain insights into the in-depth study of AMS and its potential applications in improving acoustic sensing accuracy and communication reliability across various scenarios. Understand how this research addresses limitations in sensing resolution and range due to bandwidth constraints and signal decay at inaudible frequencies.
