"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)"The objective of this research is to develop the fundamental scientific and engineering principles that will form and drive the development of k-space multifunctional acoustic wave devices as potential components in telecommunication technology with high level functionalities. The approach is based on the use of phononic crystals as parts of acoustic wave devices that can produce transformative k-space (real space) functionalities in addition to the more common spectral (temporal) functions. These novel functions arise from properties of phononic crystals such as zero or negative angle refraction as well as generation of phase locked multiple beams. This research will combine theoretical-computational methodologies and experimental techniques. The research objectives will be met by demonstrating experimentally prototype functional structures and devices. This research?s intellectual merit resides in the k-space functionality of the devices. In contrast to traditional spectral functions these new functions will transform the field of acoustic wave devices by enabling spatial filtering, beam multiplexing and logic operations in compact structures and devices as practical miniaturized and integrated components in acoustic wave systems. The investigators will conduct the research in a global context and will expose graduate and undergraduate students to international collaborations through exchange as part of a Centre National de La Recherche Scientifique (France)-University of Arizona International Associated Laboratory. The investigators will build on experience in the development of Do-It-Yourself technology kits on audible phononics to support outreach activities at high schools and science fairs with the aim of promoting science and engineering education and careers among the ethnically diverse Tucson community.

“该奖项是根据 2009 年美国复苏和再投资法案（公法 111-5）资助的”这项研究的目的是开发基本的科学和工程原理，形成并推动 k 空间多功能声波的发展设备作为具有高级功能的电信技术的潜在组件。该方法基于使用声子晶体作为声波器件的一部分，除了更常见的谱（时间）函数之外，还可以产生变换的 k 空间（实空间）函数。 这些新颖的功能源于声子晶体的特性，例如零或负角折射以及锁相多光束的生成。这项研究将结合理论计算方法和实验技术。研究目标将通过实验演示功能结构和设备原型来实现。 这项研究的智力价值在于设备的 k 空间功能。与传统的频谱函数相比，这些新函数将通过在紧凑的结构和器件中实现空间滤波、波束复用和逻辑运算作为声波系统中实用的小型化和集成组件来改变声波器件领域。 研究人员将在全球范围内进行研究，并将通过作为国家科学研究中心（法国）-亚利桑那大学国际联合实验室的一部分的交流，让研究生和本科生接触国际合作。 研究人员将利用开发可听声学DIY技术套件的经验，支持高中和科学博览会的外展活动，旨在促进图森多种族社区的科学和工程教育和职业生涯。
