摘要
我们设计的声学人工材料利用局部相位响应来控制反射声场,从而实现在三维空间上任意位置处的宽带的声学聚焦。我们设计的声学人工材料单元可以实现在2π范围内对相位的任意的调控。这种三维的声学聚焦方法在超声治疗、无损检测等领域有潜在应用。
We realize three-dimensional broadband sound focusing by controlling the local phase response over 2pi range. With the merits of simple fabrication and tunable focus, our design may be applicable to many important situations such as medical ultrasound and non-destructive tests.
