The propagation of acoustic waves is a fundamental topic in shallow ocean acoustics. We numerically demonstrate a three-dimensional zone of silence consisting of a circular tube with gradient index metamaterials attached to its rigid wall. The cloaking effect is verified by fine agreement with analytical calculations.

三维宽带声波导管斗篷

声波的传播是浅海声学的一个基本课题。我们以数值方式展示了一个由圆管组成的三维寂静区,其刚性壁上附着有梯度指数超材料。通过与分析计算的良好一致性来验证隐形效果。
