Abstract

Almost no diffraction broadening of self-collimation beams and their easy crossing with low crosstalk offer new opportunities for acoustic wave manipulation. Here, we flexibly steer the self-collimation beam based on the total internal reflection of an airborne square lattice sonic crystal. The properly designed crystal/air interface may serve well as a total internal reflection mirror of the self-collimation beam, with which we are able to achieve the highly controllable beam reversal, snaking and crossing. Our scheme can be extended to more interesting beam steering, and have potential applications in constructing high-density integrated acoustic circuits.

在二维声波晶体中灵活转向自准直光束

摘要自准直光束几乎没有衍射增宽，而且易于交叉，串扰小，这为声波操纵提供了新的机遇。在此，我们基于机载方格声波晶体的全内反射，灵活地引导自准直光束。设计得当的晶体/空气界面可以很好地充当自准直光束的全内反射镜，从而实现高度可控的光束反转、蛇形和交叉。我们的方案可以扩展到更有趣的光束转向，并有可能应用于构建高密度集成声学电路。
