【摘要】 艾里波束具有自弯曲及自聚焦等新奇特性,得到了广泛的关注。本文提出了利用上下对称的一对艾里波束实现声学聚焦的方法,并通过数值计算证明了该方法的可行性。该方法为声学聚焦的实现提供了新的途径,有望在医学治疗及声学成像中产生潜在的应用。更多还原

【Abstract】 Airy beams that exhibit many novel properties such as self-bending and self-healing have attracted extensive attentions. We have proposed a scheme to achieve acoustic focusing by using a pair of airy beams. The numerical simulations have been performed to verify the validity of the scheme, which provides a mean of achieving acoustic focusing and may have potential applications in medical therapeutic and acoustic imaging.更多还原
