在这项工作中，我们报告了奇异的声传输行为通过穿孔的硬板与准周期阵列的亚波长小孔。这一现象是由系统的长程有序引起的相干衍射引起的。实验结果与数值计算结果吻合较好。我们还对周期系统和随机系统进行了比较研究，以揭示普遍存在的本征物理。
In this work, we report the exotic acoustic transmission behavior through hard plates perforated with a quasiperiodic array of subwavelength apertures. The phenomenon is verified to be originated from the coherent diffraction induced by the long-range order of the system. The experimental results agree well with the numerical ones. We also present comparative studies on the periodical and random systems to reveal the intrinsic physics in a universal way.
