论文摘要
波的频率是理解其传播到结构化介质的关键参数。虽然超材料可以设计为聚焦或转向变形或波浪向特定位置，但在不同频率下向多个靶向位置的波转向仍然具有挑战性。在这里，我们表明随机弹性网络的修剪允许实现这种多目标，多频的声学转向。我们的研究为多频声学间材料的合理设计开辟了一条可行的途径。
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.
