【摘要】 由于具有自弯曲和自修复等新颖性质,艾里波束得到了研究人员的广泛关注,并被引入到聚焦领域。本文提出了利用多组上下对称的艾里波束实现声学聚焦的多焦点模式,并通过数值计算对该设想进行了验证。多焦点声学聚焦的研究在医学诊断治疗中具有重要的应用前景。更多还原

【Abstract】 Due to many novel properties such as self-bending and self-healing, Airy beams have attracted extensive attentions in the research field and have been used to realize acoustic focusing. We have proposed a scheme to achieve multi-foci pattern by using several pairs of airy beams. The numerical simulations have been performed to verify the validity of the scheme, which may have potential applications in many fields.更多还原
