Multi-Frequency Acoustic Steering in Rationally Pruned Disordered Networks

arXiv (Cornell University)

Abstract

The frequency of a wave is a crucial parameter to understanding its propagation to a structured medium. While metamaterials can be designed to focus or steer deformations or waves toward a specific location, wave steering toward multiple targeted locations at different frequencies remains challenging. Here we show that pruning of random elastic networks allows realizing such multi-objective, multi-frequency acoustic steering. Our study opens up a viable route to the rational design of multi-frequency acoustic metamaterials.
