Abstract

Mechanical computing has gained prominence in recent years, presenting a secondary yet viable computation mechanism in off-grid and low access environments. In this work, we present a first attempt to perform parallel mechanical computing within a prescribed acoustic domain, by exploiting time-modulated metasurfaces which enable simultaneous multi-wave beaming in distinct frequency channels. The realization of parallel processing in analog computing lays the foundation for substantial advancements in both in acoustic and optical domains, and unlocks several features which this far have been elusive in physical neuromorphic and reservoir computing.
