In this paper, we address the interaction of zero-order acoustic Bessel beams as an acoustic manipulation tool, with an active spherical shell, as a carrier in drug, agent, or material delivery systems, in order to investigate the controllability of exerted acoustic radiation force as the driver. The active body is comprised of a spherical elastic shell stimulated in its monopole mode of vibrations with the same frequency as the incident wave field via an internally bonded and spatially uniformly excited piezoelectric actuator. The main aim of this work is to examine the performance of a nondiffracting and self-reconstructing zero-order Bessel beam to obtain the full manipulability condition of active carriers in comparison with the case of a plane wave field. The results unveil some unique potentials of the Bessel beams in the company of active carriers, with emphasis on the consumed power of the actuation system. This paper will widen the path toward the single-beam robust acoustic manipulation techniques and may lead to the prospect of combined tweezers and fields, with applications in delivery systems, microswimmers, and trapper designs.
在本文中，我们研究了零阶声学贝塞尔光束的相互作用，将其作为一种声学操纵工具，与主动球形壳作为药物、试剂或材料输送系统的载体相结合，以研究作为驱动力的声辐射力的可控性。主动体由一个球形弹性壳组成，该弹性壳通过内部粘结和空间均匀激励的压电换能器以与入射波场相同的频率激励其单极振动模式。这项工作的主要目的是检验无衍射和自重建的零阶贝塞尔光束的性能，以获得主动载体的完全可操纵条件，并与平面波场的情况进行比较。结果揭示了贝塞尔光束与主动载体结合的一些独特潜力，重点是激励系统的功耗。本文将拓宽单光束鲁棒声学操纵技术的道路，并可能导致组合镊子和场的出现，从而在输送系统、微游泳者和捕集器设计中得到应用。
