Super-resolution imaging has been separately realized with two-dimensional photonic and phononic quasi-crystal flat lenses for the past few decades, but they are still utilized for independent disciplines. In this paper, Stampfli-type photonic quasi-crystal (S-PTQC) and S-PTQC flat lens are proposed. The numerical results demonstrate that the common photonic and phononic band gaps exist within two normalized frequency ranges of the S-PTQC. Moreover, optical and acoustic super-resolution imaging is achieved with the S-PTQC flat lens. The properties of acoustic super-resolution imaging are more stable compared to the optical counterpart. The proposed S-PTQC flat lens has the potential ability to manipulate electromagnetic and elastic waves, and will provide a new methodology for realizing diverse acousto-optic devices.

在过去的几十年中，二维光子和声子准晶体平面透镜分别实现了超分辨率成像，但它们仍然用于独立学科。在本文中，提出了 Stampfli 型光子准晶体 (S-PTQC) 和 S-PTQC 平面透镜。数值结果表明，在 S-PTQC 的两个归一化频率范围内存在共同的光子和声子带隙。此外，S-PTQC 平面透镜实现了光学和声学超分辨率成像。与光学对应物相比，声学超分辨率成像的特性更稳定。所提出的 S-PTQC 平面透镜具有操纵电磁波和弹性波的潜在能力，并将为实现各种声光器件提供一种新方法。
